Tilesize and Performance problems

I added the support to set the tile size.
I also added a javascript debounce function to the create map.
I ran into severe performance problems whith google maps, when I set a marker on the map and tried to zoom.
Which resulted in a crash of leaflet. This issue is already discussed in the leaflet forum, and they probably come up with a better solution, but up until now this is a quick fix for that problem.

It would be interesting if you have any better idea how to fix that problem?
