Well, you don't *need* to have this enforced (although it would not hurt 
much ;-).

An application can silently assume that there are no line segments longer than 
xxx, which will result in just not drawing line segments in some cases. This 
is probably an advantage anyway, since too long line segments almost anytime 
result in some client errors when projecting stuff. (This is true especally 
for read-only display clients like freemap).

Ciao, Imi.
