What about the following patch?

a) Page numbers from dvipng always match "\[[\d]+"
b) Glyph numbers from mktexpk always match "\[[\d]+\]".
c) No other numbers in dvipng's output will match "\[[\d]+"
d) Since you use --depth, page numbers from dvipng will always match
   "\[[\d]+[^]]", that is, will not be followed by "\]".

The provided patch searches _first_ for "\[([\d]+)[^]]" and _then_ for
"depth=([\d]+) height=([\d]+)". Bonus: will work with any previous
version of dvipng.

But your point is that another (future) helper called from within dvipng
might not heed this, or?
