static double drc_lines	(	PointType *	end,
		bool	way
	)		`[static]`

drc_lines() checks for intersectors against two lines and adjusts the end point until there is no intersection or it winds up back at the start.

If way is false it checks straight start, 45 end lines, otherwise it checks 45 start, straight end.

It returns the straight-line length of the best answer, and changes the position of the input point to the best answer.
