David Edmundson f445a99a74 Support scaling in BackgroundContrast effect
Summary:
Background contrast reads pixels from the framebuffer
we need to convert from compositor to framebuffer co-ordinates
when an output is scaled

Test Plan:
Ran the manual test in kwindowsystem. Moved window over dolphin.
Visually checked output
