	* app/tools/gimptransformtool.c
	* app/tools/transform_options.[ch]: replaced the totally unclear
	(to the user) way we used to calculate the number of grid lines
	from the value entered in the "Density" spinbutton by a system
	where the user has the choice between the number of grid lines to
	display and the spacing between the displayed grid lines. Replaced
	the "Show Grid" toggle by an option menu to choose the grid type
	from. (idea from drc on #gimp).
