New package: XtoW, a native compositing window manager (experimental)

[Jon TURNEY <jon dot turney at dronecode dot org dot uk>]

The following packages have been added to the Cygwin distribution:

*** XtoW-20121220-1
*** libxcwm0-20121220-1
*** libxcwm-devel-20121220-1

xtow is a window manager using the libxcwm library [1], which is:
* native: it integrates with native window management by putting each
top-level X window in it's own Windows window (similar to XWin -multiwindow)
* compositing: X windows with per-pixel alpha are composited into the native
DWM desktop on Windows Vista and later (e.g. a native window can be seen
through a semi-transparent X window placed over it)

At this stage, these packages will only be of interest to people who are going
to fix or report crashes.

There are lots of missing features compared to XWin -multiwindow. Notably,
there is no clipboard synchronization (although xwinclip should work).

You will notice that drawing is noticeably slower, especially of large areas,
because the image has to be fetched over the socket from the X server (this
could be avoided by putting the image in shared memory, or a shared texture)

To use:
* write an /etc/X11/xorg.conf file which specifies the dummy driver and a
screen size which is the same size as the native desktop
* start Xorg
* start xtow
* start some X clients (e.g. 'urxvt -depth 32 -bg
rgba:rgba:0000/0000/0000/4444' for a transparent terminal)
