Please explain what these functions are used for instead of what you're trying
to do with this patch.

Done.

I think we can come up with a better API than this. Please combine these two
pair of functions into one pair. And I think it'd be nice to expose it using a
"Scoped" class. ie. private API Begin/EndGpuRaster(), public API "class
ScopedGpuRaster".

Done.
