 Environment: qgis 0.9.1 Ubuntu 7.10

 Problem:

 Qgis is loading the catalogue of available SVGs for symbology only on
 startup, so if after starting Qgis a new SVG is created or a SVG is
 deleted, the catalogue is not updated accordingly and the new SVG is not
 available in the Symbologydialog. As my plugin is creating new SVGs on
 runtime, which I want to be available in the Dialog, I tried this:

 Suggestion:
 I changed qgsmarkercatalogue.cpp like this:

 Now every time my plugin is constructing a new SVG, I call the
 updateMarkerCatalogue() like this

         QgsMarkerCatalogue
 *markerCatalogue=QgsMarkerCatalogue::instance();
         markerCatalogue->updateMarkerCatalogue();

 Tested in above named environment and it worked fine.

 If this change is accepted there would probably even be the opportunity to
 do this MarkerCatalogue Update every time the Symbology Dialog is opened
 automatically???
