Garret Rieger ff3cac0ccd [subset] Fix unecessary trailing 0 bytes left by ContextFormat2 pruning.
Uneeded rules where beind removed from the count by the bytes for them was being left in the font.

Behdad Esfahbod 2e9b270a49 [hb-view] Fix cairo slanting condition
hb-draw already does slanting. If NOT hb-draw, we should slant
through cairo path.  Donno why this was untested before.

This was double-slanting with hb-draw, and not slanting without it.

Garret Rieger 51028e63e6 [subset] Retain all glyphs in preprocessed face. 2022-11-23 22:51:16 +00:00
Behdad Esfahbod 404cb99d86 [buffer-diff] Fix check for glyph flag equality
I'm not sure if the old behavior was intentional, but it was checking
that the glyph flags were a subset of the reference buffer's glyph
flags.  I don't see why that is useful.  Fix that.

Then make the buffer-verify code ignore flag differences when verifying
buffers, since our unsafe-to-concat flag at least, is conservative and
not guaranteed to be produced the same in fragments.  See:

Garret Rieger 4c49daf7cd [subset] actually use the preprocessed face in hb-subset.
Tests weren't actually using the preprocessed face due to this typo in util/hb-subset.

Garret Rieger 2c0afde737 [subset] add an inprogress accelerator to plan.
This allows subset code to cache information into the accelerator during preprocess subset. Previously the accelerator was created at the end of subsetting.

Garret Rieger 463ae07e99 [subset] In the preprocess subset call always use long loca.
Long loca is needed so that we can store the trimmed glyph bytes to allow us to safely skip trimming in the later subset.

I don't know why this check was there, but it doesn't make sense
because that function never returns 0 / false.
