Subject: [SDL] SDL window resize and flicker

I have a resizable SDL window, and when it's resized, the surface goes
black _and_ is flushed to screen before I have a chance to redraw
it. This causes flicker.

The super-small attached patch fixes this issue by avoiding a
SDL_Flip() right after the window resize. What do you think?

This SDL_ClearSurface function is only called once in the code, in
SDL_SetVideoMode, and as far as I can tell the patch doesn't introduce
other changes than getting rid of the flicker.
