cc: Deblur layers that animate-scale-down on creation.
Layers that appear at a scale 1.5 with a transform animation that would
take them to 1.0 end up drawing with the 1.5 tiling still when they
complete their animation. This happens for two reasons:
1. It uses stale data in ManageTilings to tell if the layer is animating.
2. The active tree says it has ideal tilings when it has tilings >= ideal.
We fix 1 by setting the animating draw properties flag before computing contents
scales in calcDrawProperties.
We fix 2 by not telling the scheduler that we drew with all ideal tilings if we
did not.
While fixing 2 we get rid of the tree walk in swapBuffers, by tracking
if any incomplete tiles were used in the AppendQuadsData instead.
