The Spanish version of Myst has bitmaps that use palette indices in the system reserved range. Affected pixels previously used colors from the Windows system palette instead of the bitmap's own palette, resulting in visual glitches. Bitmaps are now remapped to the screen palette which is made of the Windows reserved palette and part of the bitmap palette. The original engine used GDI's StretchDIBits with DIB_RGB_COLORS to achieve the same result. Fixes #7153.
