GPU and Shadow Mattes

[MattClark]

Good to see this finally supported on the GPU, but I notice it behaves slightly differently, not sure if this is by design or not.

In a simple example of a teapot on a matte plane, with a GI environment and a single light, It appears that matte floor does not receive GI, Certainly in the beauty pass the shadows seem to render black.. This is with the 03 Feb Nightlies.

That's correct, the GPU matte shadows will not have the GI included.
