ofParameter<void> notification loop

Hello everyone.

I'm in a situation where I create ofParameters with .:newReference() function.
With that I have both ofParameters "linked together" similar to @arturoc ofParameterLink proposal

I have no issues with that except with ofParameter, as there is no notification loop safeguard.
I've resolved this issue updating what I did in this change with the notifiy loop safeguard implemented in : https://github.com/openframeworks/openFrameworks/blob/b674f7ec1f41d8f0fcfea86e3d3d3df3e9bdcf36/libs/openFrameworks/types/ofParameter.h#L726-L766
See implementation in: https://github.com/PlaymodesStudio/openFrameworks/commit/7bbf058eb2afe5852fd7c04b8ceed0831a4fe719

My doubt is about using this approach, or using the setMethod / eventsSetValue / noEventsSetValue. Seems as a more elegant solution but, as ofParameter has no value, its use is only for triggering events noEventsSetValue is not a needed function.

What do you think about that?

Thanks!

Start with libs/openFrameworks/types/ofParameter.h at the referenced notification-loop implementation, then compare the linked openFrameworks pull request and PlaymodesStudio commit. Review how ofParameter uses setMethod, eventsSetValue, and noEventsSetValue. Done requires an agreed approach for preventing loops in linked ofParameter instances and a corresponding implementation or documented decision.
