[Qgis-developer] how to render selected feature on top of the others?

[G. Allegri]

In my application I need to let the user to select (from a table) and
zoom to a specified feature
The layer is made of a dense cloud of points, so even if the point get
selected it happens to be hidden by other (unselected) points.
Is it possible to ask the renderer to put the selected points on top
of the others?

I'm working on qgis 1.4 throgh the python bindings.
