/******************************************************************************
	PAThumbWheelCell
	
PAThumbWheel offers the functionality of Slider plus the features that you would expect from a real thumbwheel (including 2 3/4 D Graphics!).

PAThumbWheel has a linear display mode and a radial display mode and offers the ability to assign a value to the visible region of the control as well as an absolute value that the ThumbWheel will either ignore, bound to or wrap around.

PAThumbWheel can also return relative values via its -relativeIntValue & -relativeFloatValue methods. A snap back option allows mouse loops to start from and return to a base value.
