The `very pale dot' has exactly the same line thickness as lines.  A
normal text dot is thrice as big.  Are the lines in the old image
thrice as thick also?  I've tested to add the `thick' attribute to the
dotted lines, but this doesn't produce nice results (equally bad as
the -n option of pic).  So inserting

  pic linethick=1

at the beginning of the dformat block might be the solution.
