Remove scissor rect from GrPipeline. Draws can specify "fixed dynamic state" which doesn't use the dynamism at all or can specify dynamic state arrays with an entry per GrMesh. When we state other than scissor rects this will allow the caller to use a mix of truly dynamic and fixed dynamic state. So a caller that only has dynamic scissor rects doesn't need to store its remaining unvarying state in an array.

* For the atlasing test we make a DAG that looks like:
|
|
*
|
|
* RT1 with ops: 0,1,2 RT2 with ops: 3,4,5 RT3 with ops: 6,7,8
|
|
* \ /
|
|
* \ /
|
|
* RT4
|
|
* We then flush RT4 and expect only ops 0-5 to be atlased together.
|
|
* 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
|
|
* and look like:
|
|
* R G B C M Y K Grey White
