I've compared the difference in the output for .1 and .2.  The diff file is
available at
http://www.et.byu.edu/~sorensen/regtest-diff.txt
or 
http://tinyurl.com/n5zlrr

The file names are the same, but some .eps files are more than 10x bigger in
.2 than in .1.  And I didn't see *any* .png files in the directories -- the
only occurrence of png in the directory tree was ps-to-png.scm.

HTH,
