 On WinXP SP3 using QGIS 1.5.0 I get two refreshes of the mapcanvas when
 selecting and deselecting layers.

 On line 1541 of qgslegend.cpp there is a call to render the mapcanvas.
 However there is also a call to updateMapCanvasLayerSet() on line 1549.
 Should call to mMapCanvas->setRenderFlag( true ) on line 1541 be removed
 to stop refreshing the canvas twice?
