[Qgis-developer] Why QDialogProgress used in QgsVectorLayer::countSymbolFeatures ?

[René-Luc Dhont]

Hi Dev,

A new QGIS Server feature : showFeatureCount, uses the method 
QgsVectorLayer::countSymbolFeatures to display feature count in legend. 
But this feature doesn't work if a fake X server is not used.

I discovered that the method QgsVectorLayer::countSymbolFeatures 
initialized a QDialogProgress. I wondered if this was the right place to 
initialize a dialog ?
