Behdad Esfahbod 3807061d63 [ot-layout] Don't remove_output() before reverse substitution
No need anymore, because of new swap_buffers() semantics.

Just assert instead.

Behdad Esfahbod 10a9960f0a [buffer] Restructure swap_buffers()

Redefining those stock names as macros was conflicting with gcc 10

Khaled Hosny 895acdf7c7 [ci] Don’t build Cairo subproject with FontConfig on win32 cross-build
We don’t need it and it breaks the build because FontConfig renamed its
master branch and the released version of Cairo wants to build
FontConfig from master branch.

Khaled Hosny 71a6296620 [tests] Make record-test.sh work with .otf files
It hard-codes the file extension, but fonttools sunset will use .otf for
CFF fonts, so hard-code the output file from subset as well.

Garret Rieger bc06af977f [subset] speed up feature collection when tags are specified.
Precompute a feature index filter to avoid needing to iterate the feature tag list for each encountered feature index. For this particular fuzzer case speeds up feature collection from 50s to 2s.

Khaled Hosny 14f220b761 [directwrite] Support feature ranges
Code copied from hb-uniscribe.cc and adapted to use DirectWrite types.
May be there is a better way to de-duplicate the code, though I'm not
exactly sure how or if it is worth it.

Garret Rieger 675ebbeb3a [subset] don't alloc zero bytes.
It will be leaked later since hb_blob_create() won't set up the blob to cleanup since it has length zero.

Behdad Esfahbod 93e6a9bc4e Revert "Remove unneeded buffer clear_output / remove_output calls"
This reverts commit 06175b7143.

One of the sanitizers is failing. Pushing again as PR to debug.
I have suspicions.

Behdad Esfahbod 06175b7143 Remove unneeded buffer clear_output / remove_output calls
Made sure clear_output is always paired with swap_buffers.
Trying to see if we can move towards RAII-like buffer iterators
instead of the buffer keeping an iterator internally.

Behdad Esfahbod bdfed8f113 [blob] Add failing versions of create API
Fixes https://github.com/harfbuzz/harfbuzz/issues/2567

New API:
+hb_blob_create_or_fail()
+hb_blob_create_from_file_or_fail()

Use these in util/ to distinguish empty file from not-found file.
Only err on the latter.

Behdad Esfahbod d3dd936309 [coretext] Round position info
Test:

Before:
$ ./hb-shape /System/Library/Fonts/ヒラギノ丸ゴ\ ProN\ W4.ttc 1 --features="+palt" --shaper=coretext
[gid781=0@-78,0+841]
$ ./hb-shape /System/Library/Fonts/ヒラギノ丸ゴ\ ProN\ W4.ttc 1 --features="+palt" --shaper=ot
[gid781=0@-78,0+842]

After:
$ ./hb-shape /System/Library/Fonts/ヒラギノ丸ゴ\ ProN\ W4.ttc 1 --features="+palt" --shaper=coretext
[gid781=0@-78,0+842]
$ ./hb-shape /System/Library/Fonts/ヒラギノ丸ゴ\ ProN\ W4.ttc 1 --features="+palt" --shaper=ot
[gid781=0@-78,0+842]

I've verified in the font that 842 is correct.

Similar to serialize_subset() this will serialize the new object and then link it to the offset.
