[l2h] Fix for relative image paths in includegraphics?

The  graphicx package has a  \graphicspath  command, which allows
search paths for graphics to be given in the LaTeX source document.

Alternatively, you can set the  $GRAPHICS_PATH  variable in
an initialisation file.

Another possibility is to make symbolic links to the graphics
in the directory above from the directory in which LaTeX2HTML works.
This is particularly useful if you want to test  latex images.tex
after a run which did not succeed fully.

Since the  &find_file  subroutine searches all the directories in the
argument that has been fed with  $GRAPHICS_PATH , it is better to add
paths in this argument rather than adjust the $file name.

The change is safe enough for your own use, but not for distribution
to all other platforms and Perl versions.
It's also not clear to me why it is necessary, as other mechanisms
are already available.


Hope this helps,
