Detailed Description

Class that does synchronization between QgsMapCanvas and its associated QgsMapRenderer:

• changes done in map canvas settings are pushed to map renderer
• changes done in map renderer are pushed to map canvas settings

This class can be removed within API cleanup when QgsMapRenderer will not be accessible from canvas API anymore. Added in 2.4. This class is not a part of public API!
