   * Factor out AUC TeX specific code

     and provide alternatives.  This could make preview-latex work with
     Emacs' default TeX/LaTeX modes which some people prefer.  Also one
     might provide an abstraction layer that would make it possible to
     embed preview-latex's core mechanisms into Emacs calc.

   * Support other formats than just LaTeX

     plain TeX users and ConTeXt users should not have to feel left
     out.  While ConTeXt is not supported yet by AUC TeX, at least
     supporting plain would help people, and be a start for ConTeXt as
     well.  There are plain-based formats like MusiXTeX that could
     benefit a lot from preview-latex.  The main part of the
     difficulties here is to adapt `preview.dtx' to produce stuff not
     requiring LaTeX.

   * Web page work

     Currently, preview-latex's web page is not structured at all.
     Better navigation would be desirable, as well as separate News and
     Errata eye catchers.

   * Manual improvements

        - Pepper the manual with screen shots and graphics

          This will be of interest for the HTML and TeX renditions of
          the texinfo manual.  Except for maybe autoconverted ASCII art
          versions of the XBM icons, the info rendition will usually be
          restricted to text descriptions, however.

        - Fix duplicates

          Various stuff appears several times.


   * Implement rendering pipelines for Emacs

     The current `gs.el' interface is fundamentally flawed, not only
     because of a broken implementation.  A general batchable and
     daemonizable rendering infrastructure that can work on all kinds of
     preview images for embedding into buffers is warranted.  This is
     the best option for integrating the current work on `dvipng' and
     should also help with

   * Working via PDF

     Going via latexpdf/gs and a single file might be faster than the
     current latex/dvips/gs path and could come handy for previewing
     documents intended for use with pdflatex.

   * Integrate into RefTeX

     When referencing to equations and the like, the preview-images of
     the source rather than plain text should be displayed.  If the
     preview in question covers labels, those should appear in the
     bubble help and/or a context menu.  Apropos:

   * Implement context menus

     Right mouse key currently just kills previews.  Offer more options
     than that.

   * Implement LaTeX error indicators

     Previews on erroneous LaTeX passages might gain a red border or
     similar.

   * Pop up relevant online documentation for frequent errors

     A lot of errors are of the "badly configured" variety.  Perhaps the
     relevant info pages should be delivered in addition to the error
     message.

   * Store cursor locations for closed previews, restore them when
     reopening them.

   * Implement a table editing mode where every table cell gets output
     as a separate preview.  Alternatively, output the complete table
     metrics in a way that lets people click on individual cells for
     editing purposes.

   * Benchmark and kill Emacs inefficiencies

     Both the LaTeX run under Emacs control as well as actual image
     insertion in Emacs appear awfully slow.  Why?

   * Make a sane gamma (non)correction image API for Emacs

     It is currently impossible to make Emacs screen colors and
     generated colors match exactly because of gamma correction issues.
