memory stack management and will severely slow down when graphing anything complex (like sin, cos, tan).  MSIE and Opera seem to keep up 
just fine, so they get the full version.  Mozilla/Netscape will get a connect-the-dots version of the graph using a JS Graphics module.  MSIE can't 
use this method because the graphs 'drip' occasionally, so we need a separate method for MSIE. The results between the two methods vary, 
especially with graphing tangent! Also, the coordinates aren't implemented with the Mozilla version.  Ton pis! */
