[MapProxy] Disable the resampling

Hello Andrea,
I think, this is not possible.
WMS is dynamic service without scale constraint (image is created  by
server on demand). Cache is (in contrast) limited to set of predefined
scales. When you request image with scale which is not covered by cahce,
mapproxy must generate (resample) this image from existing cache levels.

As a workaround of this, you can use "denser" cache with more levels, or
disable the cache. With smaller gaps between cache levels, the resampling
effect won't be so distinct. In addition, I suggest You to look at
stretch_factor option in grid definition. By disabling cache (use source
service(s) directly in layer source without cache in a middle), mapproxy
will translate all request directly to target services, thus resampling
isn't needed (I assume dynamic, no tiled, sources).

Best wishes, David
