Removes the rotation and scaling in SnapshotAura.

It seems that the compositor already takes care of the screen
rotation and scaling. SnapshotAura doesn't need to do that.

Also, snapshot_aura_unittest.cc is not good for rotation and
scaling because the existing test just paint plain red. This
CL changes the paint content to fail if the rotation is not
handled correctly.
