Ok, when I run lilypond from the command line with the following options 
it works perfectly:

lilypond --png -dpixmap-format=pngalpha -dpreview test.ly

But when I run it from jedit using lilypondtool I get an error in the 
lilypond console: "unrecognized option: foo" where foo is whatever 
I put as the default arguments in the lilypondtool plugin options.  I'm 
putting the following in the textbox for "default arguments":

--png -dpixmap-format=pngalpha -dpreview

I don't get the error if I use a single argument like "--png", or 
"dpreview".
