Behdad Esfahbod 21346af01d [layout-cache] Adjust cost-function for recent change 2022-06-07 14:41:39 -06:00
Behdad Esfahbod bfee6839b0 [layout-cache] Cache lookahead, not input, classdef in ChainContextFormat2 
From the commit:

+    /* For ChainContextFormat2 we cache the LookaheadClassDef instead of InputClassDef.
+     * The reason is that most heavy fonts want to identify a glyph in context and apply
+     * a lookup to it. In this scenario, the length of the input sequence is one, whereas
+     * the lookahead / backtrack are typically longer.  The one glyph in input sequence is
+     * looked-up below and no input glyph is looked up in individual rules, whereas the
+     * lookahead and backtrack glyphs are tried.  Since we match lookahead before backtrack,
+     * we should cache lookahead.  This decisions showed a 20% improvement in shaping of
+     * the Gulzar font.

Behdad Esfahbod b96622d15c [layout] Use a cache for main input ClassDef of (Chain)ContextLookupFormat2 
This commit adds a per-lookup caching infrastructure to GSUB/GPOS, and
uses it to cache input ClassDef.get_class value for (Chain)ContextLookupFormat2.

For fonts heavy on use of heave class-based2 context matching, this shows
a good speedup. For NotoNastaliqUrdu for example, I observe 17% speedup.

Unfortunately not many other lookups can use a cache like this :(.

Xavier Claessens 4266f4e29a Fix check-* scripts when harfbuzz is a subproject 
When harfbuzz is a subproject paths are in the form
"subprojects/harfbuzz/src/...". Instead of removing "src/" prefix, take
the absolute path and make it relative to current source dir.
