This makes sense as a default for CLUT8 modes, but not really
for anything else. As part of the gsoc2009-16bit merge, the
default was changed to "all ones", with extra code in the SDL
backend to truncate this to the depth of the mode. However,
"all ones" (white) still isn't a very useful default for RGB modes.
So rather than jumping through hoops to provide a bad default,
it's better to remove the default altogether. Engines which relied
on the old default of 255 have been updated to specify it explicitly.

recently added (cursor) palette manager) so that the cursor can be properly
restored after returning from the GUI.
If there's any C++ magic that can keep the backend functions from being called
by anything else than these managing classes, that would probably be a good
idea. Also, since the cursor manager keeps a copy of the cursor image, perhaps
there are at least some backends that will no longer need to?
