It's fine for me, but it's hard for the host to do anything meaningful, if
I understand the argument in favour of linear coeffients correctly.
I'll keep doing it that way until told of a better way anyway.

Well, it means an extra control output, doesn't it? Or can I bind a
slider and a value-display to an input control? If so, Yay!

That was what I understood happened (from looking at Quasimodo), but I
still think there is a problem: (bad ascii art coming up)
Imagine 17 pixmaps with the slider in each position.

just obove the the slider.
slider.
But hey, you've allready implemented this, so you'd know if it was a
