Manages a full screen stereo rectangle that masks rectangles in the periphery and then reconstruct these blocks.
This allows us to shade at different rates e.g. 1x2, 2x2, 4x4
It's not as efficient or its quality as good as Variable Rate Shading (because VRS shades at lower frequency but it still evaluates the depth buffer at full resolution), but it is compatible with all HW.
Used as an optimization for VR.
