Move Surface operations into existing transaction.

Several Surface operations - notably setPosition, setSize, and show -
had been moved outside of a Surface.openTransaction/closeTransaction
window. This corrects that problem.

In addition, before animations were separated from layout the Surface
frame was computed prior to returning from relayoutWindow(). After
separation the frame was being computed during animation. This checkin
restores the frame calculation in layout.

Fixes bug 6343291.
