Revert "Revert "PixelRef now returns (nearly) everything that is currently in SkBitmap. The goal is to refactor bitmap later to remove redundancy, and more interestingly, remove the chance for a disconnect between the actual (pixelref) rowbytes and config, and the one claimed by the bitmap.""

This reverts commit 4174afb18a9746bbad2a06c0ec2d4ad35f72d790.
