21656	Abort rendering when obsolete	stoecker	team	"I sometimes need to use JOSM to display street network of whole Germany and JOSM is capable to do this, but there is a major drawback. You have to wait many seconds/minutes to get the display rendered until you can zoom in. When zoomed in enough JOSM is fast as it should be, but rendering the complete large data sets is awful.

Now I actually don't want to see the complete dataset at once, but I have to go through this step to get to the data I want to see.

My suggestion would be: As soon as input events appear which in the end will anyway cause a rerendering: Abort the current rendering and start with the new one.

@Vincent: Do you think that's feasible? Would be a big help when it takes no longer minutes to see the data I want, but only a few seconds."	defect	new	normal		Core mappaint			performance	Don-vip
