* Introduced ApplicationScale (may not be good name. CompatibilityScale? CanvasScale? Pls let me know if you have better idea)
* Changes to RootView / SurfaceView
- Makes the app believe it's running in the supported density/resolution.
- Makes the window manager believe it's running at the right density/resolution.
* Added methods to Rect/Event for scaling up/down.
Known issues:
* certain kind of images (such as nine patch for buttons) seesm to be loaded not by app, thus does not take the scale into account,
which, in turn, is causing layout issue.
* ZoomButton in MapView is rendered in wrong place
* Transparent region on Surface is not correct
* Specifying different densities in one process is not working.

We used to replace elements in the default with elements from
the overlay. This change causes us to empty the array first
so if the overlay array is smaller we don't end up with elements
from the default array showing through at the end of the array.
Ex: [A,B,C] and overlay [D] should give [D] but used to give
[D,B,C].
