Updates to help dialog.
Resolve WB-414, Volume Surface Outline not on Top in All Structures View: OpenGL's polygon offset was being used to adjust the depth buffer values of the lines representing the volume surface outline.  However, OpenGL's polygon offset does not work with lines.  So, instead, polygon offset is used when drawing the underlying volume slices to push the slices slightly away from the volume surface outline and other layers.
Eliminated NodeAndVoxelColoring methods for coloring with labels with integer data types.
Resovled WB-415 Turning On and Off Volume Labels is Not Possible
