If you run the attached test, you can see nothing drawn on webkit with texturemapper.
The rotating blue rectangle should be drawn on a separated GraphicsLayer since it has an animation property. Even though a GraphicsLayer is created for it and layer tree is structured successfully, the layer doesn't appear on screen. Because it doesn't have a change to call setNeedsDisplay for the layer. For these reason, we should call setNeedsDisplay for the layer(having animation) in proper somewhere.
As my investigation. mac port and gtk port with clutter ac work fine for this test. because I think they are call setNeedsDisplay when the drawContent value is changed.

The test verifies that the layer (rotating blue rectangle in the test case)  is actually drawn on window by comparing with the expected png result.
