    Build doxygen pictures with libgd to reduce their size. · 5b87fa62
    Alexandre Duret-Lutz authored
    Doxygen only knows how to call dot with -Tpng, while using
    -Tpng:gd produces pictures that are 10 times smaller.  Use a
    simple wrapper around dot to simplify this.
    * doc/dot.in: New file, that wrap the system's dot and replace
    -Tpng by -Tpng:gd.
    * doc/Makefile.am ($(srcdir)/stamp): Depend on dot.
    * doc/Doxyfile.in: Update to 1.6.2.
    (DOT_PATH): Set to @srcdir@ to use doc/dot instead of the
    system's dot.
    * configure.ac: Find the absolute path of dot, and generate
    the doc/dot script.
