0 is probably taken as "no data value". The "real world" coordinates of the
first row and first column are probably slightly outside the "real world"
bounding box of the original raster (you may prints their bounding box for
testing this hypothesis, as well as the "gridToCRS" transform). If this is the
case, I don't know why the Resample operation computed a bounding box slightly
outside the original bounding box. We would need to open a JIRA task with a
test
case to track this issue.
