Description
There seems some resampling going on when requesting a CRS which the server supports (with enabled OTF):

e.g. QGIS set to EPSG:4326 and requesting an EPSG:4326 image from a server that supports EPSG:4326.

WMS driver does not automatically switches to projection requested by QGIS even if it is supported by WMS server. You have to manually select the right projection when layer is added.
Preferably, the WMS driver should not only to switch to the right projection, but also automatically select the most similar projection offered by server if no one exactly matches. Anybody is aware of an algorithm or ready for use method doing that?
