Window is not moved to location specified in windowmove

[GoogleCodeExporter]

What steps will reproduce the problem?
1. "xdotool getactivewindow windowmove x y" or
   "xdotool getactivewindow windowmove x 0" or
   "xdotool getactivewindow windowmove 0 y" or even
   "xdotool getactivewindow windowmove 0 0"

One expects the window to be moved to the location specified, but it 
actually moves the window to the location x+12 and y+52.

Try repeatedly running "xdotool getactivewindow windowmove x y" and notice the 
window moving.

This happens in Debian Squeeze with Xfce 4.6.2 with xdotool version 2.20110530.1

Adding relevant details -

This is due to the window move request not being honored properly by the window 
manager. The work around requires xdotool be aware of the window 
border/titlebar sizes. In some cases this is exposed with the 
_NET_FRAME_EXTENTS information, but not all cases. I'll only support the 
_NET_FRAME_EXTENTS for now.
