Map::nudgeTransitions no longer depends on client information

Clients no longer need to provide data (eg. if gesturing or in a custom
animation) to Map::nudgeTransitions().

Upon MapContext::renderSync(), a new atomic bool 'needsRepaint' in MapData
allows thread-safe communication between Map and MapContext.
