[Inkscape-devel] NEW: sliders in tool controls

Some controls (such as the Width in Calligraphic/Tweak/Eraser tools, Tremor, Wiggle, and Mass in Calligraphic, Threshold in Paintbucket, Tolerance in Pencil) are converted from numeric editable fields into draggable sliders. As these values don't usually require much precision, this makes adjusting them much easier and faster.
