// This is a workaround to enable style sheets for knobs which are not styled knobs.
//
// It works as follows: the palette colors that are assigned as the line color previously
// had been hard coded in the drawKnob method for the different knob types. Now the
// drawKnob method uses the line color to draw the lines. By assigning the palette colors
// as the line colors here the knob lines will be drawn in this color unless the stylesheet
// overrides that color.
