Module glyph 

Glyph bitmap blitting — replaces Splash::fillGlyph2.

A glyph bitmap is either:

• AA (aa = true): one byte per pixel, containing a coverage value 0–255.
• Mono (aa = false): 1-bit-per-pixel, MSB-first packed, ceil(w/8) bytes per row.

The blit clips to the destination bitmap bounds and optionally to the Clip region.

C++ equivalent

Splash::fillGlyph2.
