Workbench: Xray: Optimize and fix implementation.
There was a method explained in the Weighted Blended Order-Independent
Transparency paper to support hardware that does not support per render
target blending function.
So now only 2 geometry passes are required instead of 3 (one being the
outline/depth fill pass).
This also fix how the blending is done. There was some premult confusion
in the implementation.
