* Cosmetic improvements
* rsx: Test vertex program flags on each draw
* rsx: Properly track changes in instancing state
- We switched from a allocate-per-draw-call to reusing the vertex input data. We need to make sure previous state does not affect validation results.
- Memcpy is too slow at this level of frequency, so just reset the attributes you're using before using them.
- Also changes the validation routine to only check attributes we're actually using.
