 In Layer.Grid.initGriddedTiles there is a line:

 var extent = this.map.getMaxExtent();

 I run a map where not all the layers have the same extent, and in
 particular the overlays won't have the same extent as the base map. So
 the above line causes the grid to be misaligned in those cases.
 Replacing this line with:

 var extent = this.maxExtent;

 makes everything work perfectly as expected. Now, I call this a bug
 but maybe there's a problem with this fix? There is also another use
 of this.map.getMaxExtent() which may also be wrong.
