Of course no. Maybe the source or target CRS are not setup like
Operations.resample(...) would expect (may be an axis order issue - this issue
popup often).

I'm not familiar with GridCoverageRenderer; I didn't wrote that class. Maybe
Simone could tell more...
I'm more familiar with Operations.resample(...). I though that it was used
under
the hood by GridCoverageRenderer, but I may be wrong. Note that
Operations.resample(...) has been modified in the last months, and I didn't had
the time to verifies those changes yet - so maybe there is something to check
there to.
I'm trying to finish some work related to metadata and referencing right now,
and will come back on the coverage package as soon as I can.
