SF: Add support for inverse mounted panels.

Add 180 rotation in SF to account for inverse mounted panels.
The framework will be unaffected and use policies for a 0 mounted
panel. SF changes the global transform and silently induces the H,V
flips. Similar flips are added to screenshots as well.

SF: Clear visible region of layer appropriately.

Clear visible region of layer having layer stack id different than
the display layer stack id to ensure that the layer won't be present
on the wrong display layer list.
