Check if CC assigned as automation

[d.healey]

Could we have a function to test if a CC number has been assigned as an automation control. I would like this so that I can have MIDI automation on custom panels and trigger a repaint only when those CCs are used. It would be even better if we could query a particular control for its automation CC number, if any.

Yup, good request. However if you call repaint in the control callback it will also be fired if the CC is moved.

aha well that makes things simpler :)

I've added a method Engine.isControllerUsedByAutomation() which might come in handy for some other things too.
