Description (last modified by )
The MgLegend component does not currently handle large maps very well (with 100s of layers). This is because of primarily 2 things:
- We are excessively doing work on the GUI thread, which is a bad thing for large maps.
- We are also not caching layer icons
We should re-use the existing tree/legend modelling, initialization and updating logic from the .net AJAX viewer.
