Title: arrowhead=tee incorrectly drawn
Submitter: Laurent Cocea
Date: Sat Jul 20 09:26:13 2002
Subsys: Dot
Version: 1.8.8
System: x86-Linux-RH 6.2
Severity: cosmetic
Problem:
Arrowhead=tee may get drawn either before (+) of after (-ญญ|) the end of the edge. Also, when edges are not vertical or horizontal the arrowhead is often in a non-square angle with the edge (--/ or even -/-).

Comments:
[erg] This is a known problem with tee arrowheads. The code for the endpoint of a spline only required that the point be within a usual arrowhead, not just touching the base. This discrepancy didn't matter as the arrowhead hid it. The tee arrowhead doesn't have this luxury. Endpoint adjustment has been refined but the problem still occurs.
Fix: Use code which provides the exact point where a Bezier crosses a line segment.
