fcd7f33bbb [subset] GDEF glyphClassDef subsetting support 
glyphClassDef uses the same ClassDef format. However, glyphClassDef table
uses predefined class values so we do not remap class values.

52b6e0baa0 When serializing cmap14 order the offsets from smallest to largest. 
Current versions of OTS fail fonts with cmap 14's who's last offset does not point to the a block at the end of the table.

84163c83d3 [draw] Skip commands and paths not contributing anything 
They aren't contributing to rendering and making issue for stroking, let's skip them
ourselves as Skia does also https://skia-review.googlesource.com/c/skia/+/268166

They are useful for extracting extents and so which that functionality won't be effected by this change.

036d868913 [draw] Add a fuzzer 
Specially checks correctness of the API semantics:
* no move happens when a path is already opened with move-to.
* no path will be left open and close-path will happen at the end of opened paths.
* no path opens with a move-to and will be closed with no length.
* paths start and ending points matches.
* no line/quadratic/cubic command will be issued when no path is started.

1f5a54c768 [gvar] fix infinite loop introduced by 11f3fca 
The attempt on removing end_points had made the code unreadable
and has intrdouced infinite, fixed by making the code clear what
it tries to achieve.

5f23a76e99 [cff] Don't remove coords const qualification 
We should find some way to audit all the const removals, perhaps by
enabling -Wold-style-cast warning on the project and turning all the
implicit const removals to const_cast.

da37880e17 [draw] Add a private bit field instead null-checking quad-to callback 
This doesn't imply the the design is good or stable just is better
to not fail due to null quad-to callback so as our quad-cubic curves
translation is currently table limited which can be revisited anytime.
