Bug#1132795: please remove "Resolution: (not specified)" line (upstream objections unfounded)

> Reformulating my #10, the phrasing “Resolution: (not specified)” is misleading: the absence of pHYs does not say there is a “not specified” value but means complete nonexistence including the tag name. Printing the line creates a bogus similarity with tags without data, tricking the reader into a belief that pHYs could contain nothing. Better, non‑arbitrary: consistency with the prior behavior (omission for absent chunks such as sBIT).

The “deliberate change” (my suspicion is that it has been sooo much looked at) trades clarity for verbosity – alas, without more insight.

If pHYs chunks not exist in the png file, not printout any info about "pHYs chunks" is also ok.

I'll try add a patch to do so and release a Debian revised release.

Requiring a user to post‑process the output of a tool, that should been acceptable.

Nothing is perfect complete, especially in the opensource world.
