Initializing the scalar bar when volume rendering
Volume rendering implies setting up a scalar field to render. If nothing was selected, the first one in the scalar field list is taken by default. However the scalar bar linked to the representation and the view was not initialized.
The scalar bar mechanism in pqDisplayColorWidget
has been turned into
a static method that is accessed by pqDisplayRepresentationWidget
when trying to set up the Volume
representation.
