There is setcolor for foreground, but how can background color be set? For C=
it would be higher 4 bits, but other architectures might have common
background color for whole image.

I think about something like in C128 Basic, where drawing functions take color
number not color value. E.g. for 160x200x4 there is palette of 4 colors from
16 available.

And what should getmaxcolor return for 160x200x4 on C64: 4 or 16?
