This _is_ old, I used gd1.8.3 when I started coding dvipng two years ago.

Ok, good. The binary needs to be linked against libpng anyway, so
there already is a -lpng test in the autoconf stuff. The problem is
that it is after the -lgd test. Newer versions of gd doesn't need to
be linked against libpng in the testing phase so I haven't noticed the
order. I'll change the order in the next version of dvipng.

The default is to produce a PNG which includes all ink put on the
'paper' and in addition the DVI origin, located 1in from the top and
1in from the left edge of the paper. This usually gives whitespece
above and to the left of the produced text/math/.... If you add
-Ttight the origin will not necessarily be included, producing neat
images.
