[Qgis-developer] lock layers for map items

[Marco Hugentobler]

Hi Paolo

This option keeps the visibility (on/off) of the maplayers. Main use case is to 
have an overview map where not all layers are visible. 

As the composer uses the central  QgsMapLayerRegistry, it is not easily 
possible to have a totally different set of layers as in the main canvas.


Regards,
Marco
