Juce uses its antialiased drawing code to draw the knob. This requires
no image resources and enables displaying the rotation precisely, it
can be scaled and it's themable (by changing the colours). I think it's
a good way to do it. I don't like realistic-looking knobs very much, to
me it looks always very 90s-Windows-VST-interface-ish, but that's a
personal preference thing I guess.
