Description of problem:
My users have figures generated by gnuplot that render correctly
in some versions of ghostscript (notably ghostscript-7.07-41 from
Fedora Core 4) but are slightly off in ghostscript-8.15.3-1.fc6.
Attached are 3 files, the original postscript code, a png of the
proper rendering from 7.07-41 and a png of the improper rendering
from 8.15.3-1.fc6. The proper rendering should show the curve intersecting
the two points on the x-axis. The incorrect rendering has the curve just
missing the second point.
I also tested with ghostscript-8.15.2-8.1 and got different but still
incorrect results. Testing with real ghostscript sources, 8.01 worked,
8.10 does not.

Steps to Reproduce:
1.View postscript file in ghostscript-8.15.3-1.fc6
