+Subject: [PATCH] Maps shouldn't load chunks
+
+Previously maps would load all chunks in a certain radius depending on
+ their scale when trying to update their content. This would result in
+ main thread chunk loads when they weren't really necessary, especially
+ on low view distances or "slow" async chunk loads after teleports or
+ other prioritisation.
+
+ This changes it to only try to render already loaded chunks based on
+ the assumption that the chunks around the player will get loaded
+ eventually anyways and that maps will get checked for update every
+ five ticks that movement occur in anyways.
