SliderAttachment when Slider has multiple thumbs

[daniel]

The Slider has different modes, described here, e.g. TwoValueVertical

I posted a solution for something like a SliderAttachment for a TwoValueSlider here:

APVTS without attachments, with respect to a TwoValueSlider

Plus adding a re-entrance flag, plus adding beginChangeGesture() and endGesture(), plus atomic safety measure, because the notification from the parameter occurs most of the time from the audio thread, vs. the slider notification come from the message thread… There is quite a bit of work involved to do it right. The above solution will: cock up when an automation is recorded, since it doesn’t know when you touch the slider might go into a feedback spiral has thread safety issues I created …
