Add a mode to running stitch that uses randomized phase and stitch length instead of even spacing. This greatly reduces moire effects when stitching closely-spaced curves in running-stitch-based fills.
Add option for randomized running stitch to:
ripple stitch
circular fill
contour fill
guided fill
auto-fill
When is randomization is not selected, ripple stitch will use even running stitch when staggers are set to 0 (default) and the stagger algorithm from guided fill (which does not look nice with a stagger period of 0) when staggers is nonzero.
Also includes fix for satin contour underlays (missing tolerance default) mentioned in #2814. This sets the default tolerance to 0.2mm, which is the largest tolerance guaranteed to be backwards-compatible with existing designs using the default inset of 0.4mm.
Original commits:
* fix satin underlay tolerance default
* Add randomized running stitch, make available in ripple stitch, circular, and contour
* add randomized guided fill
* make ripple stitch use even stitching when not staggering or randomizing.
* add random auto-fill and switch jitter parameter to a percentage (matches satin)
* fix comments
* update shapely
* pin pyinstaller to 5.13.2 (issues with macOS) (rejbasket)
* macOS: do not install shapely from binary, but remove .dylibs folder (breaks notarizazion) (rejbasket)
* dont fail on satin with fill
* fill stitch error message
* convert to satin mac issue
* auto_satin: add rung for two node old style satins
* avoid divide by zero in intersect_region_with_grating
* fix for incorrect stagger in guided fill
* better rail sectioning algorithm
* fix#1780
* fix#1816
