Khaled Hosny c3f590bb1e [arabic] Support legacy PUA shaping 
Support legacy pre-OpenType Windows 3.1-era fonts, by remapping PUA code
points in cmap table and letting our fallback shaper build the GSUB
table.

Uniscribe applies also mset-like substitution, but our fallback mark
positioning gives better results, so this is not implemented.

Garret Rieger 46d4a5e673 [subset] Convert subset plan to use a flags bit set. 2021-07-29 18:02:34 -07:00
Garret Rieger 9aa0ecef3f [subset] de-duplicate the logic that finds unicodes corresponding to requested glyphs. 
Move the logic into subset planning and then re-use the results in cmap and OS2 subsetting. Removes depedency on cmap from os2.

Behdad Esfahbod bbbea3dbd8 [minor] Rewrite set operation in OS/2 subsetting 
This patch could be nicer:
https://github.com/harfbuzz/harfbuzz/pull/2572/files

Just tiny touchup now.

Qunxin Liu 8e5bc535d1 [subset] call collect_mapping only when --gids option is used. 
collect_mapping is time consuming as it iterates all codepoints in all
cmap subtables, only trigger it when necessary

Qunxin Liu b2a965df5e [subset] Add support for "--gids" option 
cmap subsetting now retains entries associated with any glyph ids explicitly requested

Behdad Esfahbod 2bd953ff4f [metrics] Fix weird use of xor 
I believe that was a try to use one approach as fallback to other.  But
felt wrong.  Just believe what's in OS/2 table to be correct.

Add pre-opentype font pages detection code (#986) 
As Khaled's finding on #981 this is the way Uniscribe detects those fonts. This is its detection part.

Make some of implicit header uses explicit (#989) 
Splitted from #950 and #986 IIRC Chromium had a policy about this encouraging it,
not sure about automated way to detect and add them but for now lets have the needed
ones of them.
