 * CmdBox --
 *
 * Box command.
 *
 * Usage:
 *	box width [num]
 *	box height [num]
 *	box size [width height]
 *	box position [llx lly] [-edit]
 *	box values [llx lly urx ury] [-edit]
 *
 *	box <direction> <distance> | cursor
 *
 *	box move <direction> <distance> | cursor
 *	box grow <direction> <distance>
 *	box shrink <direction> <distance>
 *
 *	box [llx lly urx ury] [-edit]
 *
 *	Coordinates and sizes may be specified in any of the following
 *	units:  none (internal), "i" (internal), "l" (lambda), or any
 *	metric units (e.g., "um").  Coordinates may be integer or
 *	floating-point (e.g., "20i" or "1.5mm").  There should be no
 *	space between the value and the unit specifier (i.e., "20l",
 *	not "20 l").
 *
 *	Coordinates are usually reported relative to the root cell of
 *	the window, unless the "-edit" switch is given.
 *
 * Results:
 *	Box values are printed to the console.
 *	Tcl version returns values for the first five cases above when
 *	the optional value or values are not present.
 *
 * Side effects:
 *	May modify the location of the box tool.
