[luatex] handling resolution of jpg files

 Further to my last mail, I just tried the same test file with
latex+dvipdfmx and it works like pdftex (the clipping  is tight to the
numbered circles)  but I get the warning

extractbb:warning: JPEG: Inconsistent resolution may have specified in
Exif and JFIF: 72x72 - 120x120

So arguably it's a fault in the image file, (and not your fault:-)
although given that it's easy to produce such things and hard to spot
in advance, it would perhaps be good if things could go the same way
or error or at least warn...

In this case I just drew a couple of circles in an empty  microsoft
paint and clicked save as jpeg, so it's not as if the inconsistent
data occurred due to some complicated pipeline of image
