	* src/graphing.c: fix the scales on the axis (the precision was
	  reversed!)

	* src/graphing.c: draw the x/y axis and a dotted grid in grey.  This
	  really improves readability I think.  This should be configurable I
	  guess.

	* src/funclib.c, src/gnome-genius.c, src/genius.c: allow setting
	  default for AskString as second argument

	* help/C/gel-function-list.xml: update
