As I've found out, it was not the line clipper that was buggy, but the
program. It passed line coordinates near INT_MAX to the clipper, which behaved
as designed (which means, it didn't handle the integer overflow and went into
an endless loop).

Now the question is how to handle this stuff. Having the line clipper hang is
ugly, but handling (or checking for) integer overflows withing the line
clipper eats memory and performance. Any votes?
