Solved the performance problems by introducing the concept of a single-buffered
display, which is a fast path used for the whole-surface SDL 1.2 API.
Solved the flicker problems by implementing a backbuffer in the GDI renderer.
Unfortunately, now using the GDI renderer with a backbuffer and HBITMAPs is
significantly slower than SDL's surface code. *sigh*
