When SDL 1.3 is ready it should not be a problem
to add a SDL helper lib. that supports Rotation and
other nice things. When using OpenGL and Direct 3D
it is no problem and for 2D it is okay, when there are
only functions for 32 Bit Color, like in RotoZoom.

It makes SDL 1.3 smaller and it is okay
if SDL 1.3 supports all the 2D functions from
SDL 1.2 to make porting easy.
