So the photofont would have a red arab alphabet with a red lam, a black arab
alphabet with a black aleph, and built-in ligaturing so if you give the
glyph numbers for red lam black aleph you get the red-black lam-aleph glyph
What is the problem with the coloration controls then? They come before the
ligaturing and have to encode just one color in each glyph number they
unicode lam in red context passes thru coloration control procedure yields
red lam glyph number
unicode aleph in black context passes thru coloration control procedure
yields black aleph glyph number
and then red lam black aleph passes thru ligaturing yields multicolor glyph.
Or else I don't understand what these coloration controls are.
