First draft of the new bindings API. We'll follow this up with some API
refinements, tests, documentation, and examples.
Bindings are a new record type for establishing relationships between
two shapes so they can update at the same time.
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `feature` — New feature
### Release Notes
#### Breaking changes
- The `start` and `end` properties on `TLArrowShape` no longer have
`type: point | binding`. Instead, they're always a point, which may be
out of date if a binding exists. To check for & retrieve arrow bindings,
use `getArrowBindings(editor, shape)` instead.
- `getArrowTerminalsInArrowSpace` must be passed a `TLArrowBindings` as
a third argument: `getArrowTerminalsInArrowSpace(editor, shape,
getArrowBindings(editor, shape))`
- The following types have been renamed:
- `ShapeProps` -> `RecordProps`
- `ShapePropsType` -> `RecordPropsType`
- `TLShapePropsMigrations` -> `TLPropsMigrations`
- `SchemaShapeInfo` -> `SchemaPropsInfo`

Adds a feature flag `Measure performance` that allows us to:
- Measure the performance of all the actions (it wraps them into
`measureCbDuration`).
- Measure the frame rate of certain interactions like resizing,
erasing,....

This PR adds a slideshow example (similar to @TodePond's slides but more
on rails) as a way to put some pressure on camera controls.
Along the way, it fixes some issues I found with animations and the new
camera controls.
- forced changes will continue to force through animations
- animations no longer set unnecessary additional listeners
- animations end correctly
- updating camera options does not immediately update the camera (to
allow for animations, etc.)
It also changes the location of the "in front of the canvas" element so
that it is not hidden by the hit test blocking element.
### Change Type
- [x] `sdk` — Changes the tldraw SDK

This PR implements a camera options API.
- [x] Initial PR
- [x] Updated unit tests
- [x] Feedback / review
- [x] New unit tests
- [x] Update use-case examples
- [x] Ship?
## Public API
A user can provide camera options to the `Tldraw` component via the
`cameraOptions` prop. The prop is also available on the `TldrawEditor`
component and the constructor parameters of the `Editor` class.
```tsx
export default function CameraOptionsExample() {
return (
<div className="tldraw__editor">
<Tldraw cameraOptions={CAMERA_OPTIONS} />
</div>
)
}
```
At runtime, a user can:
- get the current camera options with `Editor.getCameraOptions`
- update the camera options with `Editor.setCameraOptions`
Setting the camera options automatically applies them to the current
camera.
```ts
editor.setCameraOptions({...editor.getCameraOptions(), isLocked: true })
```
A user can get the "camera fit zoom" via `editor.getCameraFitZoom()`.
# Interface
The camera options themselves can look a few different ways depending on
the `type` provided.
```tsx
export type TLCameraOptions = {
/** Whether the camera is locked. */
isLocked: boolean
/** The speed of a scroll wheel / trackpad pan. Default is 1. */
panSpeed: number

Followup to https://github.com/tldraw/tldraw/pull/3188 (although this
problem was there before that PR)
This does more work for RTL rendering in SVG context, especially since
we position each span one-by-one.
I had to do a bit of esoteric spelunking and it turns out
[`unicode-bidi:
plaintext`](https://developer.mozilla.org/en-US/docs/Web/CSS/unicode-bidi)
solves our issue even though it isn't really recommend to be used by web
developers. Fun times 🙃

This was @Taha-Hassan-Git 's idea originally but I thought it wasn't
necessary at the time (with our much shorter list of examples just a
couple months ago!). I think now that we have a plethora of examples
that @Taha-Hassan-Git 's original instinct here was correct and we
should a filter box.

Our undo-redo system before this diff is based on commands. A command
is:
- A function that produces some data required to perform and undo a
change
- A function that actually performs the change, based on the data
- Another function that undoes the change, based on the data
- Optionally, a function to _redo_ the change, although in practice we
never use this
Each command that gets run is added to the undo/redo stack unless it
says it shouldn't be.
This diff replaces this system of commands with a new one where all
changes to the store are automatically recorded in the undo/redo stack.
You can imagine the new history manager like a tape recorder - it
automatically records everything that happens to the store in a special
diff, unless you "pause" the recording and ask it not to. Undo and redo
rewind/fast-forward the tape to certain marks.
As the command concept is gone, the things that were commands are now
just functions that manipulate the store.
One other change here is that the store's after-phase callbacks (and the
after-phase side-effects as a result) are now batched up and called at
the end of certain key operations. For example, `applyDiff` would
previously call all the `afterCreate` callbacks before making any
removals from the diff. Now, it (and anything else that uses
`store.atomic(fn)` will defer firing any after callbacks until the end
of an operation. before callbacks are still called part-way through
operations.
## Design options
Automatic recording is a fairly large big semantic change, particularly
to the standalone `store.put`/`store.remove` etc. commands. We could
instead make not-recording the default, and make recording opt-in
instead. However, I think auto-record-by-default is the right choice for
a few reasons:
1. Switching to a recording-based vs command-based undo-redo model is
fundamentally a big semantic change. In the past, `store.put` etc. were
always ignored. Now, regardless of whether we choose record-by-default
or ignore-by-default, the behaviour of `store.put` is _context_
dependant.
2. Switching to ignore-by-default means that either our commands don't
record undo/redo history any more (unless wrapped in
`editor.history.record`, a far larger semantic change) or they have to
always-record/all accept a history options bag. If we choose
always-record, we can't use commands within `history.ignore` as they'll
start recording again. If we choose the history options bag, we have to
accept those options in 10s of methods - basically the entire `Editor`
api surface.
Overall, given that some breaking semantic change here is unavoidable, I
think that record-by-default hits the right balance of tradeoffs. I
think it's a better API going forward, whilst also not being too
disruptive as the APIs it affects are very "deep" ones that we don't
typically encourage people to use.
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `improvement` — Improving existing features
- [x] `galaxy brain` — Architectural changes
### Release Note
#### Breaking changes
##### 1. History Options
Previously, some (not all!) commands accepted a history options object
with `squashing`, `ephemeral`, and `preserveRedoStack` flags. Squashing
enabled/disabled a memory optimisation (storing individual commands vs
squashing them together). Ephemeral stopped a command from affecting the
undo/redo stack at all. Preserve redo stack stopped commands from wiping
the redo stack. These flags were never available consistently - some
commands had them and others didn't.
In this version, most of these flags have been removed. `squashing` is
gone entirely (everything squashes & does so much faster than before).
There were a couple of commands that had a special default - for
example, `updateInstanceState` used to default to being `ephemeral`.
Those maintain the defaults, but the options look a little different now
- `{ephemeral: true}` is now `{history: 'ignore'}` and
`{preserveRedoStack: true}` is now `{history:
'record-preserveRedoStack'}`.
If you were previously using these options in places where they've now
been removed, you can use wrap them with `editor.history.ignore(fn)` or
`editor.history.batch(fn, {history: 'record-preserveRedoStack'})`. For
example,
```ts
editor.nudgeShapes(..., { ephemeral: true })
```
can now be written as
```ts
editor.history.ignore(() => {
editor.nudgeShapes(...)
})
```
##### 2. Automatic recording
Previously, only commands (e.g. `editor.updateShapes` and things that
use it) were added to the undo/redo stack. Everything else (e.g.
`editor.store.put`) wasn't. Now, _everything_ that touches the store is
recorded in the undo/redo stack (unless it's part of
`mergeRemoteChanges`). You can use `editor.history.ignore(fn)` as above
if you want to make other changes to the store that aren't recorded -
this is short for `editor.history.batch(fn, {history: 'ignore'})`
When upgrading to this version of tldraw, you shouldn't need to change
anything unless you're using `store.put`, `store.remove`, or
`store.applyDiff` outside of `store.mergeRemoteChanges`. If you are, you
can preserve the functionality of those not being recorded by wrapping
them either in `mergeRemoteChanges` (if they're multiplayer-related) or
`history.ignore` as appropriate.
##### 3. Side effects
Before this diff, any changes in side-effects weren't captured by the
undo-redo stack. This was actually the motivation for this change in the
first place! But it's a pretty big change, and if you're using side
effects we recommend you double-check how they interact with undo/redo
before/after this change. To get the old behaviour back, wrap your side
effects in `editor.history.ignore`.
##### 4. Mark options
Previously, `editor.mark(id)` accepted two additional boolean
parameters: `onUndo` and `onRedo`. If these were set to false, then when
undoing or redoing we'd skip over that mark and keep going until we
found one with those values set to true. We've removed those options -
if you're using them, let us know and we'll figure out an alternative!
We're missing the export for `createShapePropsMigrationIds`, so lets add
it. This also fixes some other bits that were used in examples but not
exported properly from tldraw.
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `bugfix` — Bug fix
### Release Notes
- Expose `createShapePropsMigrationIds`, `defaultEditorAssetUrls`,
`PORTRAIT_BREAKPOINT`, `useDefaultColorTheme`, & `getPerfectDashProps`
Expose `usePreloadAssets` and make sure the exploded/sublibraries
examples uses it. Before this change, fonts weren't loaded correctly for
the exploded example.
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `docs` — Changes to the documentation, examples, or templates.
- [x] `bugfix` — Bug fix
We shouldn't be making this something you have to negate everytime you
use `useEditableText`. The TextShape can just have its custom behavior
since that's the intended usecase. (although I think that Tab there
doesn't do much anyway, but whatevs)

### Release Notes
#### BREAKING CHANGES
- The `Migrations` type is now called `LegacyMigrations`.
- The serialized schema format (e.g. returned by
`StoreSchema.serialize()` and `Store.getSnapshot()`) has changed. You
don't need to do anything about it unless you were reading data directly
from the schema for some reason. In which case it'd be best to avoid
that in the future! We have no plans to change the schema format again
(this time was traumatic enough) but you never know.
- `compareRecordVersions` and the `RecordVersion` type have both
disappeared. There is no replacement. These were public by mistake
anyway, so hopefully nobody had been using it.
- `compareSchemas` is a bit less useful now. Our migrations system has
become a little fuzzy to allow for simpler UX when adding/removing
custom extensions and 3rd party dependencies, and as a result we can no
longer compare serialized schemas in any rigorous manner. You can rely
on this function to return `0` if the schemas are the same. Otherwise it
will return `-1` if the schema on the right _seems_ to be newer than the
schema on the left, but it cannot guarantee that in situations where
migration sequences have been removed over time (e.g. if you remove one
of the builtin tldraw shapes).
Generally speaking, the best way to check schema compatibility now is to
call `store.schema.getMigrationsSince(persistedSchema)`. This will throw
an error if there is no upgrade path from the `persistedSchema` to the
current version.
- `defineMigrations` has been deprecated and will be removed in a future
release. For upgrade instructions see
https://tldraw.dev/docs/persistence#Updating-legacy-shape-migrations-defineMigrations
- `migrate` has been removed. Nobody should have been using this but if
you were you'll need to find an alternative. For migrating tldraw data,
you should stick to using `schema.migrateStoreSnapshot` and, if you are
building a nuanced sync engine that supports some amount of backwards
compatibility, also feel free to use `schema.migratePersistedRecord`.
- the `Migration` type has changed. If you need the old one for some
reason it has been renamed to `LegacyMigration`. It will be removed in a
future release.
- the `Migrations` type has been renamed to `LegacyMigrations` and will
be removed in a future release.
- the `SerializedSchema` type has been augmented. If you need the old
version specifically you can use `SerializedSchemaV1`

This PR makes a small improvement to the way we measure distances.
(Often we measure distances multiple times per frame per shape on the
screen). In many cases, we compare a minimum distance. This makes those
checks faster by avoiding a square root.
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `improvement` — Improving existing features
### Release Notes
- Improve performance of minimum distance checks.
Reworks our culling logic:
- No longer show the gray rectangles for culled shapes.
- Don't use `renderingBoundExpanded`, instead we now use
`viewportPageBounds`. I've removed `renderingBoundsExpanded`, but we
might want to deprecate it?
- There's now a incremental computation of non visible shapes, which are
shapes outside of `viewportPageBounds` and shapes that outside of their
parents' clipping bounds.
- There's also a new `getCulledShapes` function in `Editor`, which uses
the non visible shapes computation as a part of the culled shape
computation.
- Also moved some of the `getRenderingShapes` tests to newly created
`getCullingShapes` tests.
Feels much better on my old, 2017 ipad (first tab is this PR, second is
current prod, third is staging).

This PR buffs input events.
## The story so far
In the olde days, we throttled events from the canvas events hook so
that a pointer event would only be sent every 1/60th of a second. This
was fine but made drawing on the iPad / 120FPS displays a little sad.
Then we removed this throttle. It seemed fine! Drawing at 120FPS was
great. We improved some rendering speeds and tightened some loops so
that the engine could keep up with 2x the number of points in a line.
Then we started noticing that iPads and other screens could start
choking on events as it received new inputs and tried to process and
render inputs while still recovering from a previous dropped frame. Even
worse, on iPad the work of rendering at 120FPS was causing the browser
to throttle the app after some sustained drawing. Yikes!
### Batching
I did an experimental PR (#3180) to bring back batching but do it in the
editor instead. What we would do is: rather than immediately processing
an event when we get it, we would instead put the event into a buffer.
On the next 60FPS tick, we would flush the buffer and process all of the
events. We'd have them all in the same transaction so that the app would
only render once.
### Render batching?
We then tried batching the renders, so that the app would only ever
render once per (next) frame. This added a bunch of complexity around
events that needed to happen synchronously, such as writing text in a
text field. Some inputs could "lag" in a way familiar to anyone who's
tried to update an input's state asynchronously. So we backed out of
this.
### Coalescing?
Another idea from @ds300 was to "coalesce" the events. This would be
useful because, while some interactions like drawing would require the
in-between frames in order to avoid data loss, most interactions (like
resizing) didn't actually need the in-between frames, they could just
use the last input of a given type.
Coalescing turned out to be trickier than we thought, though. Often a
state node required information from elsewhere in the app when
processing an event (such as camera position or page point, which is
derived from the camera position), and so the coalesced events would
need to also include this information or else the handlers wouldn't work
the way they should when processing the "final" event during a tick.
So we backed out of the coalescing strategy for now. Here's the [PR that
removes](937469d69d)
it.
### Let's just buffer the fuckers
So this PR now should only include input buffering.
I think there are ways to achieve the same coalescing-like results
through the state nodes, which could gather information during the
`onPointerMove` handler and then actually make changes during the
`onTick` handler, so that the changes are only done as many time as
necessary. This should help with e.g. resizing lots of shapes at once.
But first let's land the buffering!
---
Mitja's original text:
This PR builds on top of Steve's [experiment
PR](https://github.com/tldraw/tldraw/pull/3180) here. It also adds event
coalescing for [`pointerMove`
events](https://github.com/tldraw/tldraw/blob/mitja/input-buffering/packages/editor/src/lib/editor/Editor.ts#L8364-L8368).
The API is [somewhat similar
](https://developer.mozilla.org/en-US/docs/Web/API/PointerEvent/getCoalescedEvents)
to `getCoalescedEvent`. In `StateNodes` we register an `onPointerMove`
handler. When the event happens it gets called with the event `info`.
There's now an additional field on `TLMovePointerEvent` called
`coalescedInfo` which includes all the events. It's then on the user to
process all of these.
I decided on this API since it allows us to only expose one event
handler, but it still gives the users access to all events if they need
them.
We would otherwise either need to:
- Expose two events (coalesced and non-coalesced one and complicate the
api) so that state nodes like Resizing would not be triggered for each
pointer move.
- Offer some methods on the editor that would allow use to get the
coalesced information. Then the nodes that need that info could request
it. I [tried
this](9ad973da3a (diff-32f1de9a5a9ec72aa49a8d18a237fbfff301610f4689a4af6b37f47af435aafcR67)),
but it didn't feel good.
This also complicated the editor inputs. The events need to store
information about the event (like the mouse position when the event
happened for `onPointerMove`). But we cannot immediately update inputs
when the event happens. To make this work for `pointerMove` events I've
added `pagePoint`. It's
[calculated](https://github.com/tldraw/tldraw/pull/3223/files#diff-980beb0aa0ee9aa6d1cd386cef3dc05a500c030638ffb58d45fd11b79126103fR71)
when the event triggers and then consumers can get it straight from the
event (like

Our font styling for dotcom vs. our examples app is _ever_ so slightly
different.
- the Inter fonts weren't being consistently linked. Sometimes we
grabbed 700, sometimes 800, sometimes 500 or 400
- the dotcom specified a default weight of 500 and line-height 1.6 which
was not specified in the our UI. this made the UI inconsistent
- furthermore, we didn't specify `text-rendering` nor `font-smooth` and
that also made things inconsistent
- finally, our buttons needed to inherit the line-height because
otherwise they were reverting to the user agent default
before:

This is the first of three textfield changes. This starts with making
the speech bubble actually have text. Also, it creates a TipTap example
and how that would be wired up.
🎵 this is dangerous, I walk through textfields so watch your head rock 🎵
### Change Type
- [x] `minor` — New feature
### Release Notes
- Refactor textfields be composable/swappable.
Adds reference docs, guide in the "Editor" article, and examples for the
side effects manager.
There are 4 new examples:
1. Before create/update shape - constrains shapes to be places within a
circle
2. Before delete shape - prevent red shapes from being deleted
3. After create/update shape - make sure there's only ever one red shape
on the page at a time
4. After delete shape - delete frames after their last child is deleted
As these examples all require fairly specific configurations of shapes
(or are hard to understand without some visual hinting in the case of
placing shapes within a circle), I've included a `createDemoShapes`
function in each of these which makes sure the examples start with
shapes that will quickly show you the side effects in action. I've kept
these separate from the main code (in a function at the bottom), so
hopefully that won't be a source of confusion to anyone working from
these examples.
### Change Type
- [x] `docs` — Changes to the documentation, examples, or templates.
- [x] `improvement` — Improving existing features
We allowed the users to customize pretty much all of our components, but
not the `DebugPanel`. We had overrides for `DebugMenu` which is
displayed inside the panel, but not for the panel itself.
I guess it makes sense to allow users to override both?

## Migration path
1. If any of your shapes implement `toSvg` for exports, you'll need to
replace your implementation with a new version that returns JSX (it's a
react component) instead of manually constructing SVG DOM nodes
2. `editor.getSvg` is deprecated. It still works, but will be going away
in a future release. If you still need SVGs as DOM elements rather than
strings, use `new DOMParser().parseFromString(svgString,
'image/svg+xml').firstElementChild`
## The change in detail
At the moment, our SVG exports very carefully try to recreate the
visuals of our shapes by manually constructing SVG DOM nodes. On its own
this is really painful, but it also results in a lot of duplicated logic
between the `component` and `getSvg` methods of shape utils.
In #3020, we looked at using string concatenation & DOMParser to make
this a bit less painful. This works, but requires specifying namespaces
everywhere, is still pretty painful (no syntax highlighting or
formatting), and still results in all that duplicated logic.
I briefly experimented with creating my own version of the javascript
language that let you embed XML like syntax directly. I was going to
call it EXTREME JAVASCRIPT or XJS for short, but then I noticed that we
already wrote the whole of tldraw in this thing called react and a (imo
much worse named) version of the javascript xml thing already existed.
Given the entire library already depends on react, what would it look
like if we just used react directly for these exports? Turns out things
get a lot simpler! Take a look at lmk what you think
This diff was intended as a proof of concept, but is actually pretty
close to being landable. The main thing is that here, I've deliberately
leant into this being a big breaking change to see just how much code we
could delete (turns out: lots). We could if we wanted to make this
without making it a breaking change at all, but it would add back a lot
of complexity on our side and run a fair bit slower

This PR adds an example demonstrating some common practices for using
tldraw as an inline block. For example, in Notion-like applications.
This includes:
- Making sure that only one editor has focus at a time.
- Always defaulting to the hand tool when you click into an editor.
- Deselecting everything when an editor loses focus.
- Hiding the UI when an editor is not focused.
- Disabling edge scrolling by default.
- Using a stripped down UI to make the most of the available space.
- Removing actions from the context menu to match the stripped down UI.
### Change Type
- [x] `documentation` — Changes to the documentation only[^2]
[^1]: publishes a `patch` release, for devDependencies use `internal`
[^2]: will not publish a new version
### Test Plan
1. Try out the **Inline behavior** example.
- [ ] Unit Tests
- [ ] End to end tests
### Release Notes
- Docs: Added an example for inline behaviour.
This diff adds a PDF editor example. It's pretty similar to the image
annotator, but is a better way to demo longer axis-locked scrolling.
There are some pretty big drawbacks to it at the moment (see the TODO
list on `PdfEditor.tsx`)
I'm going to land as-is for now, and we can iterate on it in the future.
### Change Type
- [x] `docs` — Changes to the documentation, examples, or templates.
- [x] `feature` — New feature
This diff mostly adds an image annotator example, but also has a couple
of drive-by changes:
- Added a 'use-cases' category to the examples app for this style of
mini-app
- Add `editor.pageToViewport`, which is like `editor.pageToScreen` but
works with viewport coordinates (better for `InFrontOfTheCanvas` stuff)
- Prevent the chrome side-swipe-to-go-back thing in the examples app
Some cool features of the image annotator:
- The image cannot be unlocked, and cannot have shapes places behind it
- I still need to work out a way of removing the context menu though
- Anything you place outside the bounds of the image (and therefore
outside the bounds of the export) will be greyed out
- You can't change pages
- unless you find the "move to page" action... need to fix that
- The camera is constrained! It'll keep the image roughly centered on
the screen. If you pick a very long thin image, you can only scroll
vertically. If you pick a very big one, it'll default it to a reasonable
size.

Currently, we only use native `structuredClone` in the browser, falling
back to `JSON.parse(JSON.stringify(...))` elsewhere, despite Node
supporting `structuredClone` [since
v17](https://developer.mozilla.org/en-US/docs/Web/API/structuredClone)
and Cloudflare Workers supporting it [since
2022](https://blog.cloudflare.com/standards-compliant-workers-api/).
This PR adjusts our shim to use the native `structuredClone` on all
platforms, if available.
Additionally, `jsdom` doesn't implement `structuredClone`, a bug [open
since 2022](https://github.com/jsdom/jsdom/issues/3363). This PR patches
`jsdom` environment in all packages/apps that use it for tests.
Also includes a driveby removal of `deepCopy`, a function that is
strictly inferior to `structuredClone`.

When we went from overrides-based to component based UI customisation
APIs, we didn't do the toolbar because it had some significant extra
complexity around overflowing the contents of the menu into the
dropdown. This is really hard to do at render-time with react - you
can't introspect what a component will return to move some of it into an
overflow.
Instead, this diff runs that logic in a `useLayoutEffect` - we render
all the items into both the main toolbar and the overflow menu, then in
the effect (or if the rendered components change) we use CSS to remove
the items we don't need, check which was last active, etc. Originally, I
wasn't really into this approach - but i've actually found it to work
super well and be very reliable.

being customised.
- [x] `documentation` — Changes to the documentation only[^2]
### Release Notes
- Add a brief release note for your PR here.
This PR:
- adds the export all menu items to the main menu
- removes the export all menu items from the dotcom menus
- removes the shape menu and reverts several changes from
https://github.com/tldraw/tldraw/pull/2782. This was not properly
reviewed (I thought it was a PR about hiding / showing menu items).
- fixes a bug with exporting (exporting JSON was not working when the
user had no selected shapes)
- fixes a bug that would prevent "flip shapes" from appearing in the
menu
- prevents export / copy actions from running if there are no shapes on
the page
- allows export / copy actions to default to all shapes on the page if
no shapes are selected
These changes have not been released in the dotcom yet. There's will be
some thrash in the APIs.
# Menu philosophy
In the menu, the **edit** submenu relates to undo/redo, plus the user's
current selection.
Menu items that relate to specific to certain shapes are hidden when not
available.
Menu items that relate to all shapes are disabled when not available.

### Release Notes
- Revert some changes in the menu.
Before this PR all .md files were targeted by the `.ignore` file, which
has bitten me on a number of occasions since .md files often contain
valuable information (e.g. the vscode extensions docs). This PR
unignores .md files while still ignoring _generated_ .md files like our
changelogs, the api-report files, and the generated docs sections.
Additionally, the `yarn format` and `yarn lint` commands were configured
slightly differently, which was confusing, so I've unified those and
simplified the lint.ts script at the same time.

This PR does a few things to help with performance:
1. Instead of doing changes on raf we now do them 60 times per second.
This limits the number of updates on high refresh rate screens like the
iPad. With the current code this only applied to the history updates (so
when you subscribed to the updates), but the next point takes this a bit
futher.
2. We now trigger react updates 60 times per second. This is a change in
`useValue` and `useStateTracking` hooks.
3. We now throttle the inputs (like the `pointerMove`) in state nodes.
This means we batch multiple inputs and only apply them at most 60 times
per second.
We had to adjust our own tests to pass after this change so I marked
this as major as it might require the users of the library to do the
same.
Few observations:
- The browser calls the raf callbacks when it can. If it gets
overwhelmed it will call them further and further apart. As things call
down it will start calling them more frequently again. You can clearly
see this in the drawing example. When fps gets to a certain level we
start to get fewer updates, then fps can recover a bit. This makes the
experience quite janky. The updates can be kinda ok one second (dropping
frames, but consistently) and then they can completely stop and you have
to let go of the mouse to make them happen again. With the new logic it
seems everything is a lot more consistent.
- We might look into variable refresh rates to prevent this overtaxing
of the browser. Like when we see that the times between our updates are
getting higher we could make the updates less frequent. If we then see
that they are happening more often we could ramp them back up. I had an
[experiment for this
here](4834863966 (diff-318e71563d7c47173f89ec084ca44417cf70fc72faac85b96f48b856a8aec466L30-L35)).

Comparison is not 100% fair, we don't store the intermediate inputs
right now. That said, tick should still only produce once update so I do
think we can get a sense of the differences.

N/A
Two examples:
One in the UI section that shows how to add a tool to the toolbar along
with an icon
One in the shapes and tools section that shows a simple sticker tool
with no child states
I'll go over the copy again before it's merged, but don't want to spend
too long on it right now in case the feeling is that these should both
be a single example.
Next: The [minimal
example](https://tldraw.dev/examples/editor-api/only-editor) is
currently the best example we have of a tool with child states. I think
this should be adapted and copied/moved over to the custom shapes and
tools category.
