one more step towards multiple display support
- remove dependency on cached state in validateVisibility
- get rid of mVertices and mTransformedBounds
- get rid of validateVisibility
- get rid of unlockPageFlip
- handleTransaction now returns a dirty region
- computevisibileregion now uses window-manager space
