update to PL44
changes:
Fix a bug with imagemap generation.
Replace "eq4.sym" and "eq4-2x.sym". These new LaTeX equation \ 
symbols do *not*
 use pstoepsi, ps2epsi, etc. It only requires "latex", \ 
"dvips", and "gs" to
 function.
Add the following new internal commands:
	     pstoepsi(<target_eps_path>,<src_ps_path>,<scale>)
