Andy Dodd dadf01fe95 rtgui/guiutils - Improve behavior with smooth scrolling devices ...

Devices such as trackpads will emit smooth scrolling (GDK_SMOOTH_SCROLL) events with
deltas smaller than +/-1.0 at high frequency.

Quantizing these to +/-1.0 leads to significant amplification of scroll speed to the point
of unusability

Scroll by delta instead of +/-1.0 in these cases, permitting smooth scrolling through panels that use this code

Some mice emit GDK_SMOOTH_SCROLL with deltas of +/-1.0 per detent.  This patch will not change behavior
with such devices.  However, if any mice emit deltas of smaller magnitude, the per-detent behavior will
change.
