Detailed Description

A rotary control.

position is the normalized travel proportion in [0,1] AFTER the response curve has been applied — i.e. it is what the pointer angle should be derived from, not the raw value. start_angle / end_angle are in radians in Pulp's screen convention (y-down, 0 = the +x axis, clockwise positive — the same convention painters::KnobStyle documents); the pointer angle is start_angle + position * (end_angle - start_angle).
