[josm-dev] Performance optimizations

[Petr Dlouhý]

Hello,

I tried your patch. I didn't see any big performance improvement, but  
that's probably that I wasn't watching it intensively. I have seen a  
problem, that the screen is not redrawn after deletion of the node.

I have big problem with JOSM that slowing down through time when I am  
editing large data sets and using WMS plug-in intensively. It become  
unusable after some time, and I must restart whole application. That  
didn't solve with that patch.
