class QgsLayerTreeMapCanvasBridge : QObject
{
%Docstring
 The QgsLayerTreeMapCanvasBridge class takes care of updates of layer set
 for QgsMapCanvas from a layer tree. The class listens to the updates in the layer tree
 and updates the list of layers for rendering whenever some layers are added, removed,
 or their visibility changes.

 The update of layers is not done immediately - it is postponed, so a series of updates
 to the layer tree will trigger just one update of canvas layers.

 Also allows the client to override the default order of layers. This is useful
 in advanced cases where the grouping in layer tree should be independent from the actual
 order in the canvas.
