Useful feature for SDL 1.3

I’ve been using GLUT for cross-platform OpenGL amusement. I would like to
use SDL instead, but it’s missing a Redraw event. Sometimes, especially in
interactive applications, it would be nice to only redraw the screen when
necessary. It saves X from working too hard. GLUT has its display callback,
and I think that SDL should have an SDL_RedrawEvent, to be called when any
part of the window needs redrawing. It doesn’t seem like too much of a
stretch from SDL_ResizeEvent.
