23828	[PATCH] Very slow at Wireframe view with large data set	Nzara	team	"==== What steps will reproduce the problem?
1. Have Wireframe view disabled
2. Load a large amount of data (100k nodes, 25k ways, 1k relations)
3. Zoom and Pan
4. enable Wireframe view (View-> Wireframe View)
5. Zoom and Pan

==== What is the expected result?

* GUI is same responsive in wireframe view as in normal view

==== What happens instead?

zoom to data / zoom in / zoom out / Enable wireframe view / etc. - all make the system  unresponsive for about 20 Seconds. 


==== Other observations
* All operations in normal view take a fraction of a second
* purging half the data reduces unresponsive time in wireframe view to 5 seconds
* wireframe view gets faster, if less data is visible 

==== Please provide any additional information below. Attach a screenshot if possible.
