this code is highly unlikely. it is not haile selassie.
there is some hair here. we can't just use the window's
clip region as it is, because if we are painting the border,
the border is not in the client area and so we will be excluded
when we validate the GC, and if we are painting a parent-relative
background, the area we want to paint is in some other window.
since we trust the code calling us to tell us to paint only areas
that are really ours, we will temporarily give the window a
clipList the size of the whole screen and an origin at (0,0).
this more or less assumes that ddX code will do translation
based on the window's absolute position, and that ValidateGC will
look at clipList, and that no other fields from the
window will be used. it's not possible to just draw
in the root because it may be a different depth.
to get the tile to align correctly we set the GC's tile origin to
be the (x,y) of the window's upper left corner, after which we
get the right bits when drawing into the root.
because the clip_mask is being set to None, we may call DoChangeGC with
fPointer set true, thus we no longer need to install the background or
border tile in the resource table.

* This file is a reduced version of the header file of

*
* This copy of code has been introduced to allow a clear namespace
* separation between <X11/...> and <nx-X11/...> header files.
*
* This version of the Xcomposite library header file only contains symbols
* required by nxagent and strictly avoids indirectly including
* from an X11 library that is also shipped in nx-X11/lib/.
*
* When using <X11/extensions/Xcomposite.h> instead for inclusion in
* nxagent, it will attempt pulling in the <X11/extensions/Xlib.h>.
* However, the headers of the same name from <nx-X11/...> should be
* used instead.
*
* FIXME: Once the nxagent Xserver starts using libX11 from X.Org, this
* hack can be removed.
