17553	Better support 512x512 tiles	naoliv	team	"I am unsure if this is something that JOSM needs to better support, but [https://www.openstreetmap.org/#map=18/-21.80973/-48.18637 go here] (`-21.809315, -48.186871`) and create a custom TMS layer with this:

`tms:https://api.maptiler.com/maps/b2037b15-5614-4fed-9608-9830b8dc574a/{z}/{x}/{y}.png?key=YmPoUxbTlEHlrASzv56Z`

This layer has tiles with a size of 512x512 pixels and we can see this in JOSM:

(basically we can't really see anything useful)

If, however, we use the same layer but with 256x256 tiles

`tms:https://api.maptiler.com/maps/b2037b15-5614-4fed-9608-9830b8dc574a/256/{z}/{x}/{y}.png?key=YmPoUxbTlEHlrASzv56Z`

we can see this:

Could JOSM somehow be improved to better support 512x512 tiles?
