Fixed some issues with the code, and performance is now closer to the
original implementation.
There's still a bug in surface_sdl::get_data and masked surfaces are
not yet handled properly.
And get_pix is missing a call to set_render_target(Surface);

Again, without any performance improvent, persuing this any further
appears to be a dead end. But I'll leave the branch around
nonetheless, just in case :-).
