	* src/graphing.c: Use -10 to 10 for all default ranges.  Much better
	  than PI, that was stupid.  Set minimum plot window to 1e-10 and
	  enforce it to avoid errors with computing ticks leading to
	  hanging behaviour.

	* gtkextra/*: copy new files from cvs version of gtk extra except
	  for gtkpslot which is broken, so keep our old version which works

	* gtkextra/gtkplot3d.[ch]: fix up the axis mess

	* src/graphing.c: use the new gtk extra stuff.  Produces nicer
	  plots on screen.  Initial patch was by Sebastian Dröge
	  <slomo@circular-chaos.org>
