Revert "Merge pull request #289 from hecrj/fix/cursor-events" 

`winit` seems to produce `CursorEntered` and `CursorLeft` events after
wheel scrolling for no apparent reason (?). This causes annoying flickering when hovering some widgets on a scrollable.

I should investigate this further. We are rolling back the fix for the
time being.
