13222	[Patch] Use visitor pattern for painting tiles	michael2402	team	"Migrate towards a visitor pattern.

Only the default zoom level is painted this way, the missed tiles are still painted using the old function.

Using streams and by adding a simple `parallelStream()` I was able to execute the image processors in parallel. This speeds up drawing a lot."	enhancement	closed	normal	16.08	Core imagery		fixed	gsoc-core	Don-vip bastiK stoecker
