Resizing or Redrawing the knob

[HeroofOne]

Hello. I just inherited a solution that uses Knobs and noticed a few problems with the API.

First, there is no easy way to redraw the Knobs. I found the pull request here where you mentioned that triggering "configure" on the Knob would resize the Knob. This is partially true, but it removes certain configurations like the "format" function.

I assumed that I could simply trigger "configure" with the same "format" function, but this is not the case. This "format" function seems to be disregarded and the "value" is displayed instead of the "actualValue". As do many other "hacks" that I tried. It seems the only way to preserve this "actualValue/displayValue" is to build a Knob from scratch. Again, I set my "format" function to return "this.o.displayValue", but that only seems to work for the initial creation of a Knob.

I also attempted to use relative height/width for the Knobs, but found that the code wouldn't work for our solution. It simply hard-codes the resize handler into "window", instead of providing the option to NOT automatically bind an event handler to the window or call the handler without triggering a resize to the whole window. This causes problems as we use a debounce function to avoid re-drawing too much on screen. This means that the Knobs are "resized" before the actual document, which does nothing. Additionally, this native behavior also clears the "format" function and doesn't display what it should.

I know these changes aren't likely to occur soon, but I hope that these enhancements could be made to improve the API.
