Define a custom shortcut for Compiz Window Manager

[Ralf Mardorf]

The needed packages for Karl's and my scripts are:

http://packages.ubuntu.com/xenial/wmctrl
http://packages.ubuntu.com/xenial/xdotool
http://packages.ubuntu.com/xenial/apcalc

I had no time to test it on my Ubuntu Wily, the scripts work on Arch
with
[rocketmouse at archlinux ~]$ pacman -Q calc wmctrl xdotool 
calc 2.12.5.3-1
wmctrl 1.07-4
xdotool 3.20150503.1-1

I tested a variation of the above script with openbox shortcuts and
fbpanel launchers. Workspaces aren't an issue, maximised windows aren't
an issue, but the coordinates of the window position are not always as
hoped for.

[rocketmouse at archlinux ~]$ wmctrl -m
Name: Openbox

PID: N/A
Window manager's "showing the desktop" mode: OFF

eval $(xdotool getwindowgeometry --shell $(xdotool getactivewindow))
WIDTH=$(calc "int($WIDTH*0.75)")

  "") HEIGHT=$(calc "int($HEIGHT*0.75)");
esac
wmctrl -i -r $WINDOW -b remove,maximized_vert,maximized_horz
wmctrl -i -r $WINDOW -e "0,-1,-1,$WIDTH,$HEIGHT"
exit
