Change all inner loops to call the same frame function.
Remove the draw delay code. Now that we have proper frame pacing it is
not necessary anymore to wait before drawing to make sure the previous
frame stayed on the screen long enough.
Fixes#9915, #9922, #9923.
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.
