12654	[Patch] Add layer invalidation listener	michael2402	team	"This patch allows you to register a listener on every layer that gets notified whenever that layer needs to be repainted.

This is intended to replace those MapView#repaint() calls. After changing to this system, we might use more efficient caching of the individual layers to allow e.g. the background to be re-rendered without requiring to render the osm data layers again.

It makes code cleaner as well and removes a dependency on the MapView.

I only replaced a hand full of repaint() calls, we might replace more of them in the future."	enhancement	closed	normal	16.04	Core mappaint		fixed
