Hi all,
I have created this JIRA to relax the bbox and resolution equality
constraints on coverages composing a coverageView (when JAI-EXT is enabled).

Some new satellites are producing datasets for different bands at different
resolutions.
As an instance:
https://earth.esa.int/web/sentinel/user-guides/sentinel-
2-msi/resolutions/spatial

JAI-EXT supports an ExtendedBandMerge operation which allows to merge
images not perfectly aligned or having different resolutions, by applying a
backward mapping
from the destination image to each source image.
When JAI-EXT is enabled, it would be good to relax those constraints to
support this kind of views.

Cheers,
Daniele
