Hi,

I want to do an example with OpenLayers adding a Google Maps
basic layers with a WMS overlay. The problem is that Google Maps projection
is EPSG:900913 and WMS service don't accept this projection, but EPSG:23030,
for example, is accepted.

I look through Internet and I find this example: http://www.goolzoom.com/.
In this example, in client, it is reprojected the WMS EPSG:23030 layer by:

   - Asking for three images to WMS service
   - Resampling and cutting the images returned by WMS service
   - Generating an irregular grid based in an algorithm.

Is there any solution in Openlayers to add a layer and a overlay in
different projections?

Regards,

Gorka
