/* Editor for geometry volumes and assemblies of volumes. Besides the volume
   name and line attributes, a TGeoVolume has the following editable categories 
   splitted vertically by a shutter:
   - Properties: one can edit the shape and medium components from here. It is
   also possible to change the existing ones.
   - Daughters: the main category allowing defining, editing, removing or 
   positioning daughter volumes inside the current edited volume. To add a 
   daughter, one needs to select first a volume and a matrix. Currently no check
   is performed if the daughter volume creates an extrusion (illegal for tracking).
   To remove or change the position of an existing daughter, one should simply
   select the desired daughter from the combo box with the existing ones, then 
   simply click the appropriate button.
   - Visualization: One can set the visibility of the volume and of its daughters,
   set the visibility depth and the view type. Selecting "All" will draw the 
   volume and all visible daughters down to the selected level starting from the
   edited volume. Selecting "Leaves" will draw just the deepest daughters within
   the selected visibility level, without displaying the containers, while "Only"
   will just draw the edited volume.
   - Division: The category becomes active only if there are no daughters of the 
   edited volume added by normal positioning (e.g. from <Daughters> category). The
   minimum allowed starting value for the selected division axis is automatically 
   selected, while the dslicing step is set to 0 - meaning that only the number
   of slices matter.
