Bug 1086723 - Enable asynchronous update of mask layer transforms. r=kats
- Layer::ComputeEffectiveTransformForMaskLayer now computes a delta transform
  for the mask layer's effective transform using the masked layer's shadow
  transform and base transform.  This delta is applied to the effective
  transform of the mask layer, with the same effect as if it were also
  transformed by the APZ.
Bug 1086723 - Part 2: Test. r=kats
- Reftest added to perform an async scroll and verify that the mask used
  to render the rounded corners of a fixed position element are correctly
  offset.
