Hi,
I just upgraded from tetex2.0.2 to tetex3.0 on Gentoo Linux system (from
ebuild packages of Gentoo) and now, all my figure in `.tex' are messed
up. These figures have been generated through the export function of
DIA0.94.
I tried to create a simplified test case.
Here I see the two circles to mismatch, while they have the exact same
coordinate. Is this a bug from tetex? a problem specific of my system,
etc... Thanks for your help.
It isn't just your system.
Note: Nothing else has been upgraded, only tetex since the problems
appeared.
Best Regards,
Ben

Use 'dvitype' to compare the two .dvi files.
From tetex-2.02:

while tetex-3.00 gives:
754: xxx '" [EMAIL PROTECTED] begin STP newpath 0.0 SLW 1 0 1  setrgbcolor  0 360 
17.86502 17.84808 .5 CLW mul dup 4 -1 roll sub neg 3 1 roll sub -13.29381

Note the extra 'right3' at byte 962.  This seems to come from
the '\newrgbcolor'.  For teTeX 3, \newcolor is defined using \color in
    .../texmf-dist/tex/latex/pstricks/pstricks.sty
but for teTeX 2.02 was defined using [EMAIL PROTECTED] in
    .../texmf/tex/generic/pstricks/pstricks.tex
