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*
