A couple of extra points:
1: the test
(v1 + dy) == minimum()...
will almost certainly fail on some systems, since dy is not always
+/-1. It is very often +/-1 on win32 systems, but other OS (like this
Mac) return a bigger range of values. So...
...(v1 + dy) < minimum()...
might be more like it.
2: are you sure about the sign of dy? I think it may have the
opposite sign to what you might expect, so (v1 - dy) might be more
what you'd want...
