Proper fix to support all legacy knob features

*Yay! Got the log working cleanly and made code a lot more readable.

*Added support for log and reverse log.

*Improved coloring/drawing.

*Support for dragging that is in line with the object height (legacy behavior). This actually makes sense since it poses as a circular slider whose length (or height in this case) corresponds with the movable range. It also prevents the need to use a large amount of the screen estate to change its value with a mouse. Besides, there is always a shift+click.
