Since the skin will give the plugin a cBitmap, there will also be information
about the color depth and a palette. The skin can fill the palette with the
colors it can provide, and by convention it could be
0 = background
1 = text foreground unmarked
2 = text foreground marked
3 = text background marked
or something like that. Defining more than 4 colors might be a problem
for unmodified full featured DVB cards, because there the "central area"
only has 2bpp.
