QHTML7 Graphics Scene Stress Test
One canvas, independent logical items, continuously changing transforms.

Adds/removes
0/sec
The population continuously adds and removes randomly selected items around the target load. All changes are coalesced into the scene's next animation frame.
Hierarchy and Alpha-Mask Test
Child coordinates inherit parent transforms. The outer and nested masks each use two raster passes.
Assertions
Scene tree
Mask calls
Moving child
The bright moving shapes are children of the large masked group. The smallest child switches between the root and nested masked item every three seconds; it must remain registered and render relative to its current parent throughout the reparenting operation.
