Allow the use of EGA attributes/24-bit characters alongside RGB

In a big hack (since we cannot have different pixel formats yet) we
use a pixel format that allows both 24-bit RGB (without character)
or 24-bit character with 8-bit attributes. Thus in GFX we cannot
currently have characters with any RGB color, but we can set
foreground and background individually (and it even works in EGA mode).
