Setting Palettes on Nonprimary Surfaces (Windows CE 5.0)
Palettes can be attached to any palettized surface (primary, back buffer, or off-screen plain).
Only those palettes attached to primary surfaces will have any effect on the system palette.
DirectDraw blits never perform color conversion; palettes attached to the source or destination surface of a blit are ignored.
Nonprimary surface palettes are intended for use by Direct3D Mobile applications.
