New Revision: 2906

Added:
   trunk/doc/html/images/st_crosses-math.gif
   trunk/doc/html/images/st_touches-math.gif
Modified:
   trunk/doc/reference_new.xml
Log:
Reverted html markup for mathematical expressions in ST_Touches and ST_Crosses to a gif image.  It seems unicode markup does not work well for both IE and Firefox.  The next best thing to do is to get MathML markup working.
