Fix a small bug with BitmapGraphic in the way it's calling the fill. Since fill now works properly, we need to make sure begin() is called correctly.
Also, I removed ITransformable yesterday, but let's push some of those properties on to IVisualElement directly.
QE Notes: The ITransformable change should fix some tests that aren't compiling in 3d layout
Doc Notes: None
tests: checkintests, mustella Group tests, BitmapGraphic tests (one BitmapGraphic tests was still failing for me...)
