The following program doesn't work: ... GrSetRGBcolorMode(); ... color = GrAllocCell(); ... Please tell me why?
"In the RGB model GrNumFreeColors returns 0 and GrAllocCell always returns GrNOCOLOR, as colors returned by GrAllocCell are meant to be changed - what is not supposed to be done in RGB mode."
(GRX's users manual), see also test/colorops.c
Use color = GrAllocColor(). In RGB mode you don't need to GrFreeColor().
