Subject : cc: optimize filter backing store texture allocation.
Author  : senorblanco
Commit description:
  
The backing store used for filters in cc is determined by the
primitive bounds, and the filter outsets. This means that
we may end up allocating many textures of different sizes,
defeating Skia's texture cache. Texture allocation can be
slow, so we can ameliorate the allocation pressure by
rounding width and height up to the nearest power of 2.
(This is what Skia does internally for scratch textures).
