Removes the rotation and scaling in SnapshotAura.

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.
