Honestly, it should be strictly greater than (>).  The bug you show may be
related to a different issue or in compiz in a different part of the code.
They need to leave it as greater than and fix the other problems rather than
leaving this as a work-around that affects other people.  My guess is that
someone else did a similar check in the code elsewhere or some other >=
versus > check.  If you think about this a bit then you will see that I'm
right and they need to change this back to > and fix the code elsewhere.

=======================================================
"The philosophy of gun control: Teenagers are roaring through town at 90
MPH, where the speed limit is 25. Your solution is to lower the speed limit
to 20." - Sam Cohen, inventor of the Neutron Bomb

"We maintain [privately-owned] arms largely because we seek to prevent
violence. Those that wish to disarm us do so that they may perpetrate it
with impunity." - R. Murray

"Men cannot be governed and remain men. Domesticate the wolf and he changes
both physically and mentally. His muzzle shrinks, his teeth diminish, he
loses size, speed, and strength, He grows spots. His ears flop. His brain
withers. He becomes a dog. Men are on the verge of becoming dogs -- the
changes are underway already -- unless we do something to stop it."
The Ceo Lia Wheeler, Phoebus Krumm, forthcoming

"No man ever believes that the Bible means what it says; he is always
convinced that it says what he means."
George Bernard Shaw
