tracer_bound

Input

Field: Field 3D Uniform 4-Vector Byte - A colorized volume of data
	that is ready to be sent to the tracer, to which volume bounds
	are to be added.
The Outputs:
-----------

Output

Field: As above, with volume bounds added.
The Parameters:
--------------
Thickness : Adjusts the thickness (in elements) of the frame
	that is added to the data.
Opacity Scale : This is an important port - The tracer opacity
	adjustment should not be adjusted when using this module,
	as it will not only affect the opacity of the data, but
	also that of the frame.  This adjustment adjusts the
	opacity of the data only, leaving the frame totally
	opaque.
Min X : Adds an opaque wall along the plane of minimum x.
Min Y : Adds an opaque wall along the plane of minimum y.
Min Z : Adds an opaque wall along the plane of minimum z.

Known Problems/Bugs/Limitations:
-------------------------------
Only works with Uniform Data, not with Rectilinear
Rather Slow.
The Min X/Y/Z walls should be gridded, not solid.
