91f1deca7427bc48d15c263856f567a6bab97394Jeff Conniff * Create a dial to represent an input control capable of representing a
91f1deca7427bc48d15c263856f567a6bab97394Jeff Conniff * series of intermediate states based on the position of the Dial's handle.
91f1deca7427bc48d15c263856f567a6bab97394Jeff Conniff * These states are typically aligned to a value algorithm whereby the angle of the handle's
91f1deca7427bc48d15c263856f567a6bab97394Jeff Conniff * position corresponds to a given value.
