[Qgis-developer] Deactivating multi-threaded rendering - Was: QGIS' TimeManager plugin in action

Seems code will have to move away from a timer and instead trigger
rendering on determined timeout which will trigger another timeout upon

MRT has greatly improved interaction with timemanager time slider btw.
