GSlider: Make the knob width proportional to the range, if in that mode (#288)

Browse source 
Regardless of mode, made the knob container clickable so the knob position
can be moved without dragging the knob itself.

Added a 3rd GSlider to the WidgetGallery showing the proportional mode in
action.
