onCreateProgramInfo needs to know if DMSAA will be rendering to a separate MSAA target in order to properly set up its pipeline and shaders. This CL mostly just plumbs this unformation through, but also cleans up FillRRectOp now that this information is available.

* Each op is just a solid colored rect so both the atlas and the final image should appear as:
|
|
* R G B C M Y

* with the atlas having width = 6*kAtlasTileSize and height = kAtlasTileSize.

* Note: until partial flushes in MDB lands, the atlas will actually have width= 9*kAtlasTileSize
