When a device has both a touch screen and a mouse, pointer: coarse
evaluates to false and then doesn't change even if the user begins to
use the touch screen.
In this PR pointer: coarse is replaced with any-pointer: coarse, which
checks if a touchscreen input is available. Event listeners for
touchstart and mousemove update isCoursePointer dynamically. So if the
user begins to move the mouse it changes to pointer: fine, if they then
touch the screen the pointer is returned to coarse.

This is for maintainabilty of the paths. It's hard to track down all the
places where a route is being referenced. This helps unify them so that
it's easily searchable in the codebase. This came up during the readonly
room refactor and being able to find the way a particular route was
wired through the codebase.

In some cases (when you clicked close to the current viewport area) the
minimap would not change the camera position. This is because the
`clampedPoint` calculation would offset the clicked position slightly
and then the `clampedPoint` would land inside the currently viewport.
With this change we will treat every click outside of the viewport (but
still within allowed bounds) as a change that requires use to change the
camera position.

### Test Plan
1. Use minimap in various ways to make sure it still works correctly.
The change targets the `pointerDown` event, but I did also refactor one
method that is also used by double click so it makes sense to test that
as well. Make sure you are not double clicking since we don't use the
same logic there.
- [ ] Unit Tests
- [ ] End to end tests
### Release Notes
- Fixes clicking on the minimap when we clicked just slightly outside of
the current viewport.
Fixes an issue where minimap would sometimes completely bug out. The
problem was when you resized the window height. We only had resize
observer for the minimap's canvas element, but we were missing the
observer for the window / container. This caused an issue with
[calculating the minimap page
point](https://github.com/tldraw/tldraw/blob/mitja%2Ffix-minimap-when-resizing-window/packages/tldraw/src/lib/ui/components/Minimap/MinimapManager.ts#L153)
via `getMinimapPagePoint`. They y coordinate would get incorrectly
calculated.

### Release Notes
- Fixes an issue with the minimap bugging out after you change the
window's height.
Previously, we weren't exporting migrations & validators for our default
shapes. This meant that it wasn't possible to make your own tlschema
with both our default shapes and some of your own (e.g. for custom
multiplayer). This fixes that by exposing all the migrations,
validators, and versions from tlschema.

Reworks how the readonly urls work. Till now we just used a simple
function that would scramble the slugs. Now we use a proper key value
mapping between regular and readonly slugs:
- We use two KV stores. One is for going from a slug to a readonly slug
and the other one for going the other way around. They are populated at
the same time.
- We separate preview KV stores (dev, preview, staging) from production
one. I've already created these on Cloudflare. [My understanding is
](https://developers.cloudflare.com/kv/reference/data-security/#encryption-at-rest)that
ids [can be
public](https://community.cloudflare.com/t/is-it-safe-to-keep-kv-ids-in-a-public-git-repo/517387/4)
since we can only access KV from our worker. Happy to move them to env
variables though.
- [x] Disable creating new rooms when tldraw is embedded inside iframes
on other websites (we check the referrer and if it's not the same as the
iframe's origin we don't allow it)
- [x] Fork a project when inside an iframe now opens the forked project
on tldraw.com and not inside iframe.
- [x] We allow embeding of iframes, but we now track the where they are
used via the referrer. We send this to Vercel analytics.
- [x] Improved UX of the share menu to make it less confusing. Toggle is
gone.
- [x] `/new` and `/r` routes not redirect to `/`.
- [x] This introduces a new `/ro` route for readonly rooms. Legacy rooms
still live on `/v`.
- [x] Brought back `dotcom-shared` project to share code between BE and
FE. Mostly types.
- [x] Prevent creating of rooms by entering `/r/non-existing-slug`.
- [x] Handle getting a readonly slug for old rooms. Added a comment
about it
[here](https://github.com/tldraw/tldraw/pull/3192/files#diff-c0954b3dc71bb7097c39656441175f3238ed60cf5cee64077c06e21da82182cbR17-R18).
- [x] We no longer expose editor on the window object for readonly
rooms. Prevents the users disabling readonly rooms manually.

### Test Plan
1. Make sure old readonly rooms still work.
2. Creating a readonly link from an existing room should still use `/v`
path.
3. Newly created rooms should use `/ro` path for readonly rooms. Make
sure these work as well.
4. `/r` room was disabled and redirects to `/`
5. `/new` should still work when not inside iframes.
- [x] Unit Tests
- [ ] End to end tests
### Release Notes
1. This adds new functionality for readonly rooms:
- We have a new route `/ro` for newly created readonly rooms. These
rooms no longer use the scrambling logic to create readonly slugs.
Instead we now use KV storage from cloudflare to track the mapping for
slugs -> readonly slug and readonly slug -> slug.
- The old route `/v` is preserved, so that the old room still work as
they did before.
- For old rooms we will keep on generating the old readonly slugs, but
for new rooms we'll start using the new logic.
2. We no longer prevent embedding of tldraw inside iframes.
3. We do prevent generating new rooms from inside the iframes though.
`/r`, `/new`, `/r/non-existing-id` should not allow creation of new
rooms inside iframes. Only `/new` still works when not inside iframes.
4. Forking a project from inside an iframe now opens it on tldraw.com
5. Slight copy change on the sharing menu. We no longer have a toggle
between readonly and non-readonly links.
6. `editor` and `app` are no longer exposed on the window object for
readonly rooms. Prevents users from using the `updateInstanceState` to
escape readonly rooms.

This reverts commit 741ed00bda.
This was causing a bug with computed's not getting invalidated
correctly. To reproduce:
- Draw a rectangle
- Hold alt to drag out a duplicate
- Delete the duplicate
We'd then get errors and sometimes a crash where the indicator continued
trying to render a now-deleted shape.
### Change Type

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!
These were needed when the docs lived in a different repo, but they
don't any more so we can get rid of them.

This PR improves the "back to content" behavior. Rather than using an
interval, we now add a "camera-stopped" event that triggers the check.
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `improvement`
### Test Plan
1. Create some shapes, then move the camera to an empty part of the
canvas.
2. Check that the back to content button appears.
3. Ensure that the back to content button does not appear when the
canvas is empty.
This is a huge perf win, and it came to me while procrastinating on
making dinner.
The idea is that we can skip checking the parents of a computed value if
- it is being dereferenced during a reaction cycle
- the computed value was not traversed during the current reaction cycle
This more than doubles the speed of the webgl minimap render on my
machine (from 2ms down to like 0.8ms).
This will make the biggest difference for anything that derives a value
from a large collection of other computed values where typically only a
small amount of them change at one time (e.g. iterating over all the
shape page bounds to compile an RBush)
Most code paths where we see a big chunk of `haveParentsChanged` in
flame graphs should be much faster after this.

5. Do this by dragging shapes that have arrows bound to them (arrows
should uncull), groups (shapes within them should uncull), frames.

- Fix culling.
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)

This PR includes a "soft preload" feature for icons, where icons will be
loaded when the canvas first mounts. The component will not wait for
icons to finish loading before showing the editor, but this should help
with "pop in" on menu icons.
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `improvement` — Improving existing features
### Test Plan
1. Load the component
2. After load, open a menu for the first time
3. The icons should immediately be visible
### Release Notes
- Improve icon preloading
(this is a PR redo of https://github.com/tldraw/tldraw/pull/3424 which
got messed up a bit)
It doesn't quite feel like this is the right fix but it does solve the
issue. I was trying to see if `getShapeAtPoint` needed more work but the
further I went in that rabbit hole it seemed like I shouldn't touch that
code without causing a bunch of disruption at the moment.
Specifically, the code that does `Check labels first` in Editor.ts is a
little obscure (lines 4384-4397). It only checks a couple specifics
shapes (with certain combinations, i.e. a geo with "none" fill) _and_ it
doesn't check `hitLabels` which also maybe feels wrong? I tried
unraveling it but there's a lot of code relying on it at the moment to
mess with it in the stickies work.
(I was looking at https://github.com/tldraw/tldraw/pull/1910 and
https://github.com/tldraw/tldraw/pull/1806 for historical context fwiw)

The fix here was that we need to check if we're editing before
dispatching the pointer down event. This is some leftover DNA from code
when we had textareas always present and when
tl-svg-container/tl-html-container wasn't around. The
`setPointerCapture` was originally fixing a bug where dragging a shape
using the textlabel as the origin would start to breakdown when you got
to UI toolbar/panel.
Also, turns out we don't need the `setPointerCapture` anymore because of
the same reason.

This PR fixes alt-duplicating shapes not working if you pointer-down'd
on their text label.

This was necessary before but with latest refactors it doesn't help
anything. Also, it causes a minor issue with document title:

This PR uses an additional ArraySet to make capturing parent
relationships faster for computeds with more than a handful of parents.
Seems to result in an overall ~20% speedup of the `maybeCaptureParent`
function in normal usage.

### Release Notes
- Slight performance improvement to reactivity bookkeeping.
Something was bothering me a bit with the discussion around sqrt's being
slow. Looks like `Math.hypot` has a performance cost associated with it.
Looking at the Chromium source code:
https://chromium.googlesource.com/v8/v8/+/4.3.21/src/math.js?autodive=0%2F%2F#19
and
https://source.chromium.org/chromium/chromium/src/+/main:v8/src/builtins/math.tq;l=36?q=math&sq=&ss=chromium%2Fchromium%2Fsrc:v8%2Fsrc%2F
it looks like maybe we'd be avoiding the multiple arguments that can be
passed into Math.hypot which is maybe the source of the perf hit.
Also, interestingly in `math.tq` you can see it doing this funky sqrt
calculation: `Float64Sqrt((a / max) * (a / max) + (b / max) * (b / max))
* max` - I think that possibly is trying to avoid some overflow in some
cases with bigger numbers, but also possibly with a perf hit.
[edit]: OK, actually on Firefox, doing sqrt seems slower - but digging
more into this, it looks like doing `** 0.5` instead of `sqrt` is much
faster.
