[ka-Map-users] Handling large raster data sets

[Paul Spencer]

The changes in config.php also affect init.php and tile.php.  At the  
same time as the config changes, I made a change to how the _map and  
_layer constructor functions accepted arguments, so that affected  
kaMap.js.  I don't think there were changes beyond that.

Cheers

Paul
