COPY is the fastest, but overrides any kind of transparency keying. It directly writes into the framebuffer. Should only be used for certain applications, like bottom layers.
BLITTER uses a custom BitBlT algorithm for the SSE2 instruction set. Automatically generates the copying mask depending on the alpha-value. Any alpha-value that's non-zero will cause a non-transparent pixel, and all zeros are completely transparent. Gradual transparency in not avaliable.
ALPHA_BLENDING uses SSE2 for alpha blending. The slowest, but allows gradual transparencies.
Sets the rendering mode of the TileLayer.
