0 Enable Aero Snap (Ubuntu 10.10 & 10.04 only)

In Windows 7, you can click and drag a window to the left or right edge of the desktop and it will fill half of the screen, or snap a window to the top edge of the desktop and it will be maximized.
In Ubuntu 11.04, you can click and drag a window to the left, right or top edge of the desktop to achieve the same result, but in Ubuntu 10.10 or 10.04, you need some tweaking as follows.

   2. Command line 1, paste WIDTH=`xdpyinfo | grep 'dimensions:' | cut -f 2 -d ':' | cut -f 1 -d 'x'` && HALF=$(($WIDTH/2)) && wmctrl -r :ACTIVE: -b add,maximized_vert && wmctrl -r :ACTIVE: -e 0,$HALF,0,$HALF,-1
