Subject: [PATCH] render: ensure scroll region’s endpoint is valid after a window resize

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.

Based on commit https://codeberg.org/dnkl/foot/commit/e2baa6523875aaa13b6b7db80b7985978b8ee492
