Title: Fix redraw-bug in split-panes on Retina displays.

The check for resized frame sometimes failed when a horisontal split
-pane is in use, since it might have non-integer height due to
fractional pixels - possibly only in scaled resolutions.

In my case, this resulted in only the bottom three lines being scrolled,
while the rest of the pane remained static.
