Map glyph bitmap in LookUpGlyphBitmap even when unsuccessful
CFX_FaceCache::LookUpGlyphBitMap should remember its unsuccessful glyph
bitmap calculations. This is especially important if there are a lot of
repeated requests for the same glyph with large bitmaps (which means
long calculations in freetype). With this CL, the pdf in the bug below
will be rendered quickly.
