MFEKglif v1.1.1-beta1 — “Metafontverse”

This release is made on the occasion of the merger of aa517ff, fixing the user-visible portion of what turned out to be a very serious issue in MFEK's internals: we were creating corrupt .glif's in a few cases, eventually leading to erroneous filing of fonttools/fonttools#2497 (comment).

Therefore, the bug could not wait for @eliheuer to patch, and received my immediate attention.

glifparser was totally rethought, and as a consequence gained a Kurbo encoder/decoder, despite linebender/norad#211 et seq. It now has many new traits, such as RefigurePointTypes, IntoXML and SplitKurboPath.

Among bugs fixed:

• pasting of closed VWS paths no longer crashes MFEKglif
• handle colocation buggy I/O (996d4c3)
• glyph width imgui congruence (14e1f91)

The most prominent new feature is a totally remodeled Shapes tool.
