	* app/vectors/gimpcoordmath.[ch]: Introduced function to compare
	two gimpcoords

	* app/vectors/gimpstroke.[ch]: virtualized gimp_stroke_close.

	* app/vectors/gimpbezierstroke.c: made the _close function check,
	if there is an unneeded segment (CCA-Sequence with all the same
	coordinates) at the gap to be closed. If so, remove it.
