[SDL] Color to B&W - Addendum - Solved, sorta

[Lilith Calbridge]

I took a different route on this to make sure that the screen surface
and the background surface were both of the same format.  I simply
created the background surface by using SDL_ConvertSurface() to clone
all the attributes of the screen surface.

Still mysterious since they were both created using the same
parameters.
