Re-enable DisplayList properties.

Re-enabling DisplayList properties last week caused some app
errors due to the way that some transforms were being handled (specifically,
those coming from the old Animations and ViewGroup's childStaticTransformation
field). This change pushes *all* transform/alpha data from View.draw() into
the view's DisplayList, making DisplayLists more encapsulated (and correct).
