Steps in strokes

[Boudewijn Rempt]

When working on a paint paintop Wet & Sticky I realized that we don't 
currently have a way to tell the paintop how many times the paintop has been 
exececuted in the current stroke. We'll need something that starts counting 
on tool-down, informs the paintop where we are in the stroke and lets the 
paintop inform the tool back about the current state.

This would enable not only interesting things like loading a brush with a 
finite amount of "paint", but also transfering paint from the canvas back 
onto the brush, and even painting with gradients as in the Gimp.

What would be best: counting steps, or using the distance traveled in pixels? 
And how shall we combine this with the curve smoothing in KisPainter?
