Fix view/proj delayed update bug, clean up view frustum setup
Track total cull time
Better balancing of depth test tasks by striping
Clear depth buffer in rasterizer workers
Make mVisible the RasterizeAndDepthTestAABBox return value instead of state
Depth test: do z-near trivial accept test early (right after transform)
HelperSSE const correctness
Factor out common computations from IsTooSmall into BoxTestSetup
No need for persistent mpXformedPos in TransformedAABBoxSSE, just keep them on the stack.
TransformedAABBoxSSE move mCumulativeMatrix to the stack too
Compute object-space bbox corners instead of storing them.
