Ebrahim Byagowi 86c40b3a1d [fuzz/draw] Call _get_glyph_extents
Other render related APIs also may be added also later such
as ot-color and future rendering things.

Ebrahim Byagowi 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.

Ebrahim Byagowi 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.
