RE: [AD] NewAPI Poll

Context switches are inherently slow, but I don't think it matters here:
- AGL can trivially store the current BITMAP* and compare the incoming BITMAP*. If they match, no need to do anything.

- There would be no context switches anyway, since we won't be using pbuffers in the first place.

With FBO, no context switching is needed: The same context executes the whole time. The only differences is that the current target for rendering can be selected as one (or more) of the previously defined textures.

Personally, I don't care much. I'm pretty sure we can convert one into
the other. I'm more worried about things like threads and various
resource allocations on non-Windows platforms - I know very little about
those. Someone with more experience should weigh in.

Bob,
You would know - is doing a context switch on OpenGL slow or not? I think having a state-based system would naturally lead to fewer switches.
