[MapProxy] poor WMS-Quality

The degradation of quality is usually from the srs of the source WMS not
matching the srs of the cache as a result mapproxy must warp the image
generated from the source WMS which is never optimal.  This can be defined
using supported_srs in the source section.

You can also bypass the cache when defining a layer and use the wms source
directly, if this is done all WMS requests will be forwarded to the backend
WMS resulting in no quality loss.
