The compositor's visible-widget map now stores each widget's region together with its already-clipped visible rectangle, clipped to the screen bounds, and drops widgets with an empty rectangle. Cut calculation uses those rectangles directly instead of intersecting region and clip again, and the render-iteration method yields rectangle and strips rather than region, clip and strips. Three test files are updated.

Future affected installed Toad/frame pairing remains separate and belongs to Heis. No frame/CPU gain or full performance claim.
