	* app/tools/tools-utils.[ch]
	(gimp_tool_motion_constrain): Generalized to allow a variable
	number of lines for snapping, and rewritten to make snapping
	happen more intuitively; snap the shortest distance rather than
	only horizontally or vertically.
	(gimp_tool_utils_point_to_line_distance): New helper function.

	* app/tools/gimpblendtool.c
	* app/tools/gimpmeasuretool.c
	* app/tools/gimppainttool.c: Adjust to the new function signature.
