QTile rendering slow off-screen #36

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. use qtile renderer
2. zoom in on a region far away from the data set

My guess is, that some expensive off-screen drawing takes place ( place labels? 
).

I can investigate further if you want to.

Fixed by revision 448. The bug was in the index code into the qtile database. 
For empty tiles it was returning a reference to the smallest enclosing tile 
rather than 0.
