SDL_Palette- Color palette for 8-bit pixel formats
Number of colors used in this palette
Pointer to SDL_Color structures that make up the palette.
Each pixel in an 8-bit surface is an index into the colors field of the
SDL_Palette structure store in SDL_PixelFormat. A SDL_Palette should never need
to be created manually. It is automatically created when SDL allocates a
SDL_PixelFormat for a surface. The colors values of a SDL_Surfaces palette can
be set with the SDL_SetColors.
