allow to pass 'round' parameter in ttGlyphPen, optimize for noRound 2023-06-08 11:41:07 +01:00

drop oncurve if it's impliable either before OR after rounding 
ofter the rounding gives us an opportunity to make an oncurve impliable, for points that were not equidistant become so after round, so why not take it!

_getCoordinatesAndControls: make sure coords are rounded toInt() as gvar expects 
ufo2ft will no longer send varLib already-rounded master glyf tables (to give it an opportunity to compute implied oncurves on the pre-rounded coords) so when retrieving coordinates off the glyf table in order to compute gvar deltas we have to round

must update start = last + 1 in dropImpliedOnCurvePoints

also check endPtsOfContours in dropImpliedOnCurvePoints 
as per review https://github.com/fonttools/fonttools/pull/3147#discussion_r1214708207

Also, don't do same work multiple times when dropping points from flags/endPtsOfContours arrays since these are supposed to be the same for all interpolatable glyphs

move dropImpliedOnCurvePoints function to glyf table module 
so it can be used by client code on multiple glyf Glyph objects regardles of TTGlyphPen

8e981a1b28 [transform] Change the DecomposedTransform skewX sign to match Transform 
Unfortunate but for consistency's sake.

This deviates from VarComposite convention.
