* adds new options to Params: "TRIM after" and "STOP after"
* adds tooltip support to Params
* inkstitch now includes libembroidery and can directly output any supported file type
* this avoids the need for `libembroidery-convert` and compiling embroidermodder!
* TRIM support for DST format (inserts 3 JUMPs)
* STOP command supported as an extra color change that the operator can assign to code C00
* TRIMs cause the following jump stitch not to be displayed in the Embroidery layer
The simulation window is scaled to fill the available space on the screen. In
the Params dialog, the simulation window sits to the right of the Params window
and fills the remaining space.
There is no __sys.stderr_backup__ defined in the [Python sys] module. __save_stderr()__ adds a variable by that name which is a bit unconventional but it does work. This PR changes __restore_stderr()__ to read that data from the same variable. Without this change, __restore_stderr()__ will probably raise a NameError at runtime because __stderr_backup__ is an undefined name.

Switching to a cooperative model. This has the downside that a long
patch computation will cause the simulate window to take longer to
update, but in practice the longest this will be is a couple of
seconds (for a very complicated autofill region).
The problem with this approach is that sometimes the SystemExit happens down
inside shapely and it complains bitterly (on stderr). May have to rethink.
The Embroidery Params filter now pops up a full GTK dialog. This alows it to
load existing values in the selected shapes and present them to the user. The
user can also load and save presets.
If selected shapes have differing values for a given param, the values are
presented in a dropdown so the user can select one to apply to all.
Split into classes for Fill, Stroke, and SatinColumn. Renamed params to be
the same across XML attributes and OptionParser. Added distinct stitch length
params for satin underlay. Renamed "satin underlay" to "contour underlay" and
split out "center walk underlay" and "zigzag underlay".
The code is ten times more readable, parameters make more sense, and everything
is specified by the user in millimeters. Basically, everything is way better.
* added "flip" option for fills to start stitching in upper left rather than right
* line up rows in abutting fills properly
* handle intersect_with_grating intersection result that is a line or single point (skip row)
* skip endpoint marker tags in SVG files (subtags look like paths)
* dashed stroke indicates running stitch (<=0.5 width still works but is deprecated)
* in running stitches, add a stitch at apex of sharp corners
Previously, each row in a fill region was offset by a random amount. This
looks better than not offsetting at all (which will create visible columns of
stitches), but humans are very good at finding patterns in randomness. The
result is that fill regions look weird.
This commit instead carefully orders the stitches in fill regions such that
each row's stitches are offset by half of max_stitch_length from the previous.
There are also a couple of other miscellaneous fixes and features in here --
sorry about that.
