Hi , looking at your utf8 test page and any output from webify.pl , I dont  
see any definition of background colour or opacity. Neither do I see any  
comment about the background of a plot in gnuplot help function.

Where does the very light grey b/g I see using ksvg come from and why is  
Opera's transparant redering wrong?

TIA.
