	 * gtkextra/gtkplotdata.c: Fix drawing data with no connector, then
	   plot the points only, also fix plotting data with one value only,
	   finally fix clipping if both endpoints of a segment are out of
	   bounds.

	 * src/graphing.c: Add LinePlotDrawPoints function

	 * help/C/genius.xml: Document LinePlotDrawPoints, Also add
	   documentation and examples for EulersMethodFull and RungeKuttaFull
	   on how to use LinePlotDrawLine or LinePlotDrawPoints.  YELP IS
	   BROKEN so the links don't work.  The reason for shouting here
	   is that filing bugs for yelp is useless (these bugs have been filed
	   for well over a year, and nobody touched them at all).  I'm
	   thinking of just installing html docs.  Actually I'm thinking of
	   moving away from this incredibly broken DocBook nonsense and
	   moving to LaTeX, where I could actually do more math to explain
	   things and it would be a lot easier to edit.
