Comment (by rtb):

 I have a case where Quantum shows an electrical network with devices
 represented by SVG symbols.  It's imperative to know which symbols are
 selected and which are not.  I'd like to propose a couple of alternatives
 besides "re-coloring" the SVG symbol.

 One approach follows the lead of the identify features tool and simply
 places a marker on top of selected symbols.  I've managed a work-around in
 a Python plugin by catching the map canvas selectionChanged() signal and
 doing just that: I maintain a list of markers (!QgsVertexMarker)
 designating SVG symbols currently selected.

 A second approach would add an option in the symbology tab for users to
 specify the symbol to represent selected features.
