Fixes T91632 by stopping the sample correlation between dimensions which was causing rendering artifacts on simple scenes.

Fix T91632: Stops the sample correlation between dimensions which was causing rendering artefacts on simple scenes.

This is done by increasing the amount of jitter the Cranley Patterson Rotation is allowed to add. Also, it uses the y dimension of the of the sample table for 1D sampling which causes further decorrelation between dimensions. As an additional measure the x and y dimensions are swapped randomly to provide further decorrelation.
