Log Message:
update to latex-mk-1.2.

Changes are:

* Fixed a bug which prevented the POST_BIBTEX_HOOK hook from actually
  doing anything
* Dropped -Ppdf from the default DVIPS_FLAGS. Users who wish to keep
  -Ppdf as part of DVIPS_FLAGS can add it to the site configuration
  file, user configuration file, or project Makefile.
* Added DVIPDFM_ENV variable for running @code{dvipdfm} inside a
  customized environment.
* Preliminary Rich Text Format (RTF) output support. The new rtf target
  will use latex2rtf to produce an RTF version of your document. Use this
  when sending your documents to the text-formatter-challenged.
* Fixed a bug where a list of figures, list of tables, and table of
  contents were sometimes not fully up to date in the final output.
* Added support for using ImageMagick to convert JPEG and PNG files to
  EPS for inclusion in a document.
