WIDGET MANIPULATION METHODS ###.

def directtools.DirectManipulation.xlate2D	(		self,
			state
	)

def directtools.DirectManipulation.xlateCamXY	(		self,
			state
	)

Constrained 2D motion perpendicular to camera's image plane
This moves the object in the camera's XY plane if shift is held
Moves object toward camera if control is held

def directtools.DirectManipulation.xlateCamXZ	(		self,
			state
	)

FREE MANIPULATION METHODS ###.

Constrained 2D motion parallel to the camera's image plane
This moves the object in the camera's XZ plane
