render: ensure scroll region’s endpoint is valid after a window resize

Browse source 
If we had a non-empty bottom scroll region, and the window was resized
to a smaller size, the scroll region was not reset correctly.

This led to a crash when scrolling the screen content.

Fix by making sure the scroll region’s endpoint is within range.
