Title: Some generic tools for enable

This adds a couple of generic but useful tools that allow dragging the mouse to directly affect some value (either in abstract, or a Float trait in particular).

Plus for additional responsiveness, exposes the current mouse position via the current window and the current event. This allows tools which have to track the mouse closely to not lag so much (although it doesn't fix the problem completely during rapid movement).
