PartRenderingEngineTests tests patch v1

Test case to reproduce the problem.
Comment 2 Remy Suen CLA 2010-10-29 14:34:48 EDT 
The composite is set with a FillLayout initially in TrimmedPartLayout's constructor.

Then WBWRenderer's getUIContainer(MUIElement) method magically decides to swap the layout out for something else.

Gone stale and released an updated version to HEAD. The CCE has been fixed by the changes from bug 333496.
