* 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
