 Writing a Python plugin to allow the user to translate a whole vector
 layer by a given shift I use the translateFeature() of the QgsVectorLayer
 class but if the layer is zoomed the function translates only the
 visualized features.

 I use the following code:

 vlayer = iface.activeLayer()

 provider = vlayer.dataProvider()
 attrs = provider.attributeIndexes()
 provider.select(attrs)

 f = QgsFeature()

 while provider.nextFeature(f):
         error_code = vlayer.translateFeature(f.id(), delta_x, delta_y)


 If the feature to translate is not one of the visualized features, the
 error_code is 1 and the feature is not translated.
