Hello, I build a map with Geoserver/Openlayers. I use the tiled layers  
wich metatile = 14 and gutter = 100.
If my map is requested from a device with retina display (ipad air,  
macbook...), the metatiling option seems to be ignored: on every tile is  
rendered a label. The result is, that all labels are repeated several time.
The problem is, that openlayers request tiles with dimension 512x512  
instead of 256x256, while in the gridSet the dimensions are 256x256.  
Openlayers simply double the sizes if on retina display. I could force  
openlayers to use always 256x256, but the tile would be probably blurred.

I tried to configure another gridset with same resolutions and dimensions  
512x512 and I added this gridset to my layer, so that the layer have now 2  
gridsets with same resolutions and different tiles sizes. Unfortunately  
does not not work.

The question is: can I say openlayers to use another gridset if on retina  
display?
There is maybe another solution?

Regards Tommaso
