ICE has been updated to make use of the GeometryVizService to create a
GeometryVizCanvas when creating a geometry editor. Also, the
viz.service.jme3 bundle has been merged into the viz.service.geometry
bundle, as neither the mesh nor reactor editor will need to share any of
thsoe classes with the geometry editor.
