	* gtkextra/gtkplot.[ch]: add freeze/thaw functions since otherwise
	  we may hang and eat all memory on recalculating ticks needlessly
	  when changing both range and ticks.

	* src/graphing.c: use freeze/thaw to avoid hangs and huge memory
	  leaks.  On parametric plots, squish the graph a little and move
	  the legend below the plot.

	* NEWS: update
