Hi Noralf,

I forgot, but I have a two-tone (black/red) e-ink display here, and I
also have a 3-bpp RGB TFT display.

Should we add maybe R2 and R3? (or R3/R8 for number of colours?)

I'm particularly considering the 3-bpp RGB panel for GUD use now, and
while it will surely work with say a 16-bit RGB mode many bits will
be wasted in the process.

What are your thoughts? Would you take a patch for that now, later, never?
