Set the potmeter values already when the mouse button is pressed instead of waiting for it to be released.

This gives a more intuitive behaviour on clicking and dragging.

As mentioned in an earlier discussion, due to v/hpotmeter button jumps on grabbing I'm not endorsing it. I'm just posting for trialling.

Tested, appears fine, and no bad side effects detected. Btw. while focusing on the button, the phase image (of course) jumps, too. In fact, originally the value jumps, and then button / phase image correctly follow; that's all OK. The basic question regarding this now seems to me: Should we allow clicking on potmeters at all, or only dragging. Perhaps we can come back to that at some time later. It was a hard piece of work, thanks for collaboration and have a good break. So long, Hans-Dieter
