[uniscribe] Use unique font name

When installing per-process fonts using AddFontMemResourceEx(),
if a font with the same family name is already installed, sometimes
that one gets used.  Which is problematic for us.  As such, we
now mangle the font to install a new 'name' table with a unique
name, which we then use to choose the font.

During GSUB, if a ligation happens, subsequence context input matching
matches the new indexing.  During GPOS however, the indices never
change.  So just go one by one.

Fixes 'dist' positioning with mmrtext.ttf and the following sequence:

[uniscribe] Fix buffer allocation

Email from Jonathan Kew:

My cygwin build kept aborting on certain test words when run with the
uniscribe backend. Turned out this was caused by a bug in the allocation
of scratch buffers in hb-uniscribe.cc.

Commit 2a17f9568d9724e045d2c1d660e007f3acd747d9 introduced a new line

  ALLOCATE_ARRAY (SCRIPT_VISATTR, vis_attr, glyphs_size);

but it failed to account for this in the computation of glyphs_size
(the number of glyphs for which scratch buffer space is available),
with the result that the vis_clusters array ends up overrunning the
end of the scratch buffer and clobbering the beginning of the buffer's
info[].

AFAICS, the vis_attr array is not actually used, so the simple fix is
to remove the line that allocates it. (If/when we -do- need to use
vis_attr for something, we'll need to add another term to the earlier
calculation of glyphs_size.)

With this patch, the uniscribe backend runs reliably again.

11 years agoIf variation selector is not consumed by cmap, pass it on to GSUB

If variation selector is not consumed by cmap, pass it on to GSUB

This changes the semantics of get_glyph() callback and expect that
callbacks return false if the requested variant is not available, and
then we will call them back with variation_selector=0 and will retain
the glyph for the selector in the glyph stream.

Apparently most Mongolian fonts implement the Mongolian Variation
Selectors using GSUB, not cmap.

https://bugs.freedesktop.org/show_bug.cgi?id=65258

Note that this doesn't fix the Mongolian shaping yet, because the way
that's implemented is that the, say, 'init' feature ligates the letter
and the variation-selector.  However, since currently the variation
selector doesn't have the 'init' mask on, it will not be matched...
