BLF: Do Not Cache Unused Rendered Glyphs
The loading of a font size or style renders bitmaps of the characters
0-255 and stores them in a cache. But glyphs 128-255 in this cache are
not accessible. What used to be ansi high-bit characters are now multi-
byte UTF-8 sequences.
Therefore this patch reduces the glyph_ascii_table size to 128 and
only caches characters 32-127, the visible portion of ASCII, which
greatly reduces the time to load a font.
See D12189 for more details.
