ViewRoot now does a fade animation between a snapshot of the previous
layout to the new one when its content rect changes.
Also tweaked some things in the window manager to fix problems in
deciding when to animate the movement of a window and when not to.

This introduces a small new feature for ScaleAnimation allowing
the scaling factor to be expressed as a percentage of the object
(which is the same as the existing float interpretation), a
percentage of the container, or a fixed dimension. Maybe not
useful for anything else, but I needed it for this.
Also fix a bug in how transformation matrices were propagated
from the Animation to Surface Flinger, so that rotate and skew
animations will actually work. :p

Lots of work for no visible change in behavior, but now we can
do some fancier stuff...
Also allow rotation in all 4 directions.
