GM15: nasty resampling when downloadig from WMS

When downloading files from a WMS server using "export raster", the images get downloaded in fixed 512 px tiles from the WMS server. The algorithm for this is based on the new OGC pixel size of 0.28 mm.

When exporting to the WMS server's original pixel size, based on DPI (2.54*96), it drivers GM15 into resampling and quality loss.

When loading the WMS the normal way (for viewing), the images get loaded in the correct pixel size with image size of the current view. So there is no resampling.

I think, this is a bug, since GM15 shouldn't resample incoming WMS data.
