bug#5721: Feature request: Function that returns absolute coordinates

[Andreas Politz]

Hi,

I made another patch, see below.  I build it with GTK and X-tool-kit and
tested it on Xmonad, fluxbox and compiz, also on Windows 7.  In all
cases `window-inside-absolute-pixel-edges' seems to report the correct
x-y values, i.e. the absolute position of the beginning of the text
area.
