src/cursor.c: Fix branch condition for out-of-view selecting/dragging

Instead of using the stored view for comparison use the actual surface.

Before this patch, there were situations where the branch intended for
out-of-window text selection / scrollbar dragging was used even though
the cursor never left the surface.

Partly fixes #340
