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.

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.

2742c81624 Fix page_map corruption in hb_set_t during process(). 
If a process operation results in less pages then the current set has, it will likely corrupt the page_map since it overwrites page_map entries ahead of where it's processing. This fixes that problem by removing page_map entries that will be dropped. Then dropping orphaned pages and re-indexing retained pages.

[subset] Avoid incorrectly dropping cmap for NotoColorEmoji.ttf 
NotoColorEmoji.ttf uses two cmap subtables

 Format 14 | Platform ID 0 | Platform Encoding ID  5
 Format 12 | Platform ID 3 | Platform Encoding ID 10

This combination results in the cmap table being dropped during subsetting despite being valid/required.
