TGlyphCache

TGlyphCache very significantly improves text rendering performance over directly accessing TFontReader. It does this by parsing font files only once for each accessed character and caching the returned glyphs at the specified font height, and Y-axis inverted too as is needed for rendering in the Image32 library.
