Things still to do to fix up xhdvi:

3. Fix URL support so that networked files can be
   retrieved, Web browser started automatically etc.
   do networking internally? Or rely on Web browser to do it all?

   -- Done with a kludge (call to WWWBROWSER environment variable)
   but perhaps that's all we need?

4. Postscript support in the xdvi windows? Check on xdvik???

5. Figure out what to do about fonts - Pick a standard location,
   collect together a few megabytes of standard TeX fonts,
   and package it with the distribution. Plus, allow for networked
   fonts (perhaps a generalization of the absolute path names that
   can currently be used to find virtual fonts?)

----------
Things to do to improve things generally:

Sort out a convenient page-size/font-size (what does
   mosaic choose) and make that the default? Can we
   do some kind of combining with TeX to let it know
   what page size we're expecting? Except that some
   tex constructs will look really bad on the wrong size
   page - oh well...
