Dan,

Your approach changes a very strong restriction to a strong one.
IMO there is a way to change it to a very weak one,
at least for the kernel of the graphics library :

     color components <= 64
     color component bits <= 16

See gxcindex.h Revision: 1.7.2.2, Mon Jun 20 22:47:12 2005 UTC (2 months, 1

Igor.
