tdf#119745: Fix touchpad scrolling for Slides and Pages panes.

Use fractional lines scrolled to calculate distance to scroll view,
instead of jumping forward or backward a full page every call based on
sign. Also fixes existing bugs: horizontal pane can scroll too far to
right; and snapping pane from vertical to horizontal can break scrolling
if view partially scrolled.
