This patch adds the ability to swap buttons (for left
handed, or right handed people who just like their
mouse on the left side).
Buttons of the mouse on my main machine are swapped via
modmap(1) for left-handed operation, buttons on the
ther (XP) machine are also swapped via CPL applet -
since i tend to access it via KVM from time to time,
however then i use rdesktop double translation takes
place and this patch sortof offsets for this behavior.
