I am in the process of basing Project Looking Glass on the Xorg 6.8 server.
I would like to integrate this code into Xorg 6.8. All of my code is enclosed in
#ifdef LG3D (which you can verify by reviewing the diffs below). By default this
symbol is undefined. Therefore, this change is very low risk. The integrate of
this code will greatly assist me in producing future products which are based on 
the X org server.

> 2004-08-12  Deron Johnson <deron.johnson@sun.com>
> 
> 	* include/extensions/Imakefile
> 	* include/extensions/lge.h
> 	Add client header file for the Project Looking Glass Extension (LGE).		   
> 	
> 	* lib/Xext/Imakefile
> 	* lib/Xext/Xlge.c
> 	Add extension request API for Project Looking Glass Extension (LGE).
> 
> 	* config/cf/X11.tmpl
> 	Add the build switch BuildLg3d which indicates whether Project Looking
> 	Glass code (#ifdef LG3D) is to be compiled into the X server. This currently 
> 	defaults to NO (i.e. do not compile LG3D code) into the X server
> 	
>         * programs/Xserver/composite/compalloc.c
> 	Add code to zero out contents of the backing pixmap.
> 	
>         * programs/Xserver/composite/compwindow.c
> 	Fix bug in compCheckRedir. Note: this is not LG3D-specific code.
> 	It is a bug fix recommended by keithp.
> 
>         * programs/Xserver/composite/cw.c
>         * programs/Xserver/composite/cw.h
> 	Fix FUNC_EPILOGUE.
> 	Use LG3D-specific MoveWindow and ResizeWindow.
> 
>         * programs/Xserver/composite/cw_ops.c
> 	Fix bug in EPILOGUE macro. Note: this is not LG3D-specific code.
> 	It is a bug fix recommended by keithp.
> 
>         * programs/Xserver/composite/Imakefile
>         * programs/Xserver/composite/lg3dwindow.c
> 	Use LG3D-specific MoveWindow and ResizeWindow. These avoid calling 
> 	into the DDX during window movement and resizing. This prevents 
> 	Display ID plane group paintin from occuring, which prevents 
> 	nasty holes in the 3D environment.
> 
> 	* programs/Xserver/dix/Imakefile
> 	Added request dispatching debug code.
> 	
> 	* programs/Xserver/dix/events.c      
> 	Add code to specially handle the event stream when running in
> 	LG3D mode.
> 	
> 	* programs/Xserver/dix/window.c      
> 	Add code to null out the cursor image when running in LG3D mode.
> 	Redirect various window operations on override redirect windows to
> 	the window manager.
> 	
> 	* programs/Xserver/dix/ds.c
> 	* programs/Xserver/dix/ds.h
>         * programs/Xserver/dix/socketpicker.c
> 	New files which provide routines to route device events to the 
> 	LG3D display server and back again.
> 
>         * programs/Xserver/dix/xytosubwin.c 
> 	A new file which provides a routine which, given the top-level 
> 	window in which the pointer lies, determines the lowest descendent
> 	in which the pointer lies.
> 	
>         * programs/Xserver/hw/xfree86/common/xf86Xinput.c
> 	Routes device events to the LG3D display server and back again.
> 
>         * programs/Xserver/mi/miinitext.c
> 	Configures the Project Looking Glass Extension (LGE).
> 
>         * programs/Xserver/mi/mivaltree.c
> 	Prevents the ClipList and BorderClip shapes of the parent of
> 	a redirected window from being updated. This is necessary to 
> 	avoid exposures on the pseudo-root window created by the
> 	Display Server, which can lead to nasty "holes" in the 
> 	Display ID plane group of the device.
> 
>         * programs/Xserver/miext/damage/damage.c
> 	Implements a hack to prevent PaintWindow from calling into the
> 	DDX. This avoids nasty "holes" in the Display ID plane group of 
> 	the device.
> 
>         * programs/Xserver/Xext/Imakefile
>         * programs/Xserver/Xext/lge.c
>         * programs/Xserver/Xext/lgeint.h
> 	Provides the request handlers for the Project Looking Glass 
> 	Extension (LGE).
