[Bug-plotutils] libplot patches

[Diomidis Spinellis]

Hi,

The enclosed patch

- Corrects a long-standing Postscript bug by adding a colon missing from 
the BeginResource line.

- Fixes SVG compatibility by introducing a comma missing from the line 
output and required by the standard.  This causes problems with the 
Firefox browser.

Kind regards,
