Use the MathTransform returned by GridCoverage.getGridGeometry().getGridToCRS()
for transforming pixel coordinates to geographics coordinates, or
MathTransform.inverse() for the opposite way. Use the static methods in the CRS
utility class for transforming a Rectangle using the above MathTransform.
