NAME
	Generate label - make a geom label object

SUMMARY
	Name	Generate label
	Type	Input
	Inputs	NONE
	Outputs	LabelGeom - 	geom

	Parameters
	Name		Type	Default	  Choices
	Label		text			:
	Size    	float	  0.05	 0.0 -- 1.0
	X Pos		float	  0.0	-1.0 -- 1.0
	Y Pos		float	  0.0	-1.0 -- 1.0

DESCRIPTION
	Generate label creates a geom object describing a label
	object. This label is a title, that is it has a fixed 
	position on the screen, regardless of viewpoint transformations.
	This module provides a portion of the functionality of labels
	in the geometry viewer, but adds the ability to generate 
	labels automatically. This is useful for putting up frame
	or time-step numbers.

PARAMETERS

	Label (text)
	The text string to be displayed.

	Size (float)
	The height of the displayed label, in the range 0.0 - 1.0.

	Xpos (float)
	The X position of the center of the label. -1 describes the
	left side of the window; 1 describes the right side of of the
	window.

	Ypos (float)
	The Y position of the label. -1 describes the bottom of the
	window; 1 describes the top of the window.

OUTPUTS
	LabelGeom - geom

EXAMPLE NETWORKS

	This network displays a label in a geometry window.
