Which raises a question.  In my phylogeny package, we have some tree-drawing
programs that can write a bunch of file formats.  We'd like to have one that
writes a vector format that can be read by lots of drawing programs.  For
the moment, the only one that we have that is widely used out there is PICT.

Is there some other vector format that has wide support?   At the moment,
if a Windows user wants to use our programs to write out a file that
will be read into a Windows drawing program, I recommend that they choose
the PICT file format.  This is scary but works for many Windows drawing

Is there some other format that it is more useful to support (for vector
drawing on non-Mac systems)?   Computer Graphics Metafile (CGM)?
