SDL units out of spec

[JazzMaster]

The color - and effectively "color modes" are out of spec with SDL.
Further low color modes "seem non-functional?"- so I wonder if this is a GL issue, like with palettes...will investigate further.

I know that the SDL code is out of spec to the OGL code- this im working on.
Say goodbye to DWords, unless needed. Hello to SDL_Color records/structs instead.
