Subject: nx-X11/programs/Xserver/hw/nxagent/Handlers.h: fix stack smashing
 related to different data type sizes between Xserver and Xlib.

While on the X server side we were expecting a 32bit value, the Xlib side in
nxcompext wrote a 64bit integer to the 32bit location, hence overwriting
"random" data on the stack (most notably the return adress.)

We can work around this by using the Xlib-based Window data type on the
server-side as well, but this problem is likely a more general one.

Calling functions from libcompext in nxagent sounds like a bad idea. Other code
locations might well be affected by issues alike to that as well.

In order to silence compiler warnings, use a "macro hack" for overriding the
"Window" type in NXlib.h.

Subject: Properly enable/disable Xinerama support in nxagent via cmdline
 options provider in Xserver/os/utils.c.

  * Xinerama defaults to enabled, using RRXineramaExtension
    (i.e. cmdline option: +rrxinerama).
  * Cmdline option -rrxinerama disables Xinerama support entirely.
  * Cmdline option +xinerama switches from RRXineramaExtension to
    PanoramiXExtension.
  * Cmdline option -xinerama is actually non-functional (i.e. the
    default).
  * If the nx/nx option "xinerama" is handed over to nxagent,
    then Xinerama is only switched on if that given option enables it
    (value: 1) _and_ if either of the Xinerama extensions (PanoramiX
    or RRXinerama) has been initialized (via cmdline options above).

 Fixes ArcticaProject/nx-libs#117.
 Fixes ArcticaProject/nx-libs#134 (makes flawed PR#134 obsolete).

Subject: Move each screen's root-window pointer into ScreenRec.

 Backported from X.org:

 commit e7fae9ecc42ab5e73b89117722dbf4117d928f9a
 Author: Jamey Sharp <jamey@minilop.net>
 Date:   Sat May 22 00:26:28 2010 -0700

    Move each screen's root-window pointer into ScreenRec.

    Many references to the WindowTable array already had the corresponding
    screen pointer handy, which meant they usually looked like
    "WindowTable[pScreen->myNum]". Adding a field to ScreenRec instead of
    keeping this information in a parallel array simplifies those
    expressions, and eliminates a MAXSCREENS-sized array.

    Since dix uses this data, a screen private entry isn't appropriate.

    xf86-video-dummy currently uses WindowTable, so it needs to be updated
    to reflect this change.

Subject: hw/nxagent/NXresource.c: remove caching of drawables and graphics
 contexts. The security checks simply bypass the cached values so they are
 unused. Required code de-duplication in nxagent. (Will be fixed by
 ArcticaProject/nx-libs#120 later on).

Subject: [render] Split out filter finding from filter setting.

 Backported from X.org:

 commit acda790e430b2a18c7c35379f6e538f3d01ff221
 Author: Keith Packard <keithp@keithp.com>
 Date:   Fri Mar 14 13:46:30 2008 -0700

    [render] Split out filter finding from filter setting.

    To prepare for RandR using filters in transforms, split out
    code paths so that the RandR code can validate the filter name and
    parameters during the transform set operation so that use of the filter
    later will not have unreportable errors.

Subject: Move matrix operations from X server to pixman 0.13.2, handle RandR
 transform matrices in floating point.

 Backported from X.org, inspired by:

 commit 9ffc6719390df8fdd0a5295a7a7a0eaea792be45
 Author: Keith Packard <keithp@keithp.com>

    Move matrix operations from X server to pixman 0.13.2

    pixman 0.13.2 now holds all of the matrix operations. This leaves
    the protocol conversion routines and some ABI stubs in place

    Handle transform failure when computing shadow damage area.

    PictureTransformBounds can fail, when this happens, damage the entire screen
    so that the shadow gets repainted correctly.

 commit fa6a1df209bd74da1d545982cca437afc2198cc1
 Author: Keith Packard <keithp@keithp.com>
 Date:   Fri Mar 21 02:35:28 2008 -0700

    Avoid overflow in PictureTransformPoint. Fix PictureTransformIsIdentity.

    PictureTransformPoint computes homogeneous coordinates internally, but fails
    to handle intermediate values larger than 16.16. Use 64 bit intermediate
    values while computing the final result at 16.16 and only complain if that
    result is too large.

    PictureTransformIsIdentity was completely wrong -- it was not checking for
    identity transforms at all.

    Handle RandR transform matrices in floating point.

    RandR matrix computations lose too much precision in fixed point;
    computations using the inverted matrix can be as much as 10 pixels off.
    Convert them to double precision values and pass those around. These API
    changes are fairly heavyweight; the official Render interface remains fixed
    point, so the fixed point matrix comes along for the ride everywhere.

 commit 97ab0c6eff870b52c0383b63a78cec49059b2545
 Author: Keith Packard <keithp@keithp.com>
 Date:   Tue Mar 18 15:15:40 2008 -0700

    When converting from double to fixed, round carefully.

    This reduces the matrix representation error after inverting a
    transformation matrix (although it doesn't eliminate it entirely).

    Perhaps we should extend Render to include 64-bit floating point transforms...

 commit 160252d94f04acc95f0a4e0f884ff565a5aa0744
 Author: Keith Packard <keithp@keithp.com>
 Date:   Mon Mar 17 23:03:56 2008 -0700

    Add matrix inversion function (uses doubles)

    The obvious matrix inversion function, coded using doubles to avoid fiddling
    with fixed point precision adventures.

 commit ff9d1cd843a9b0aba69a3d788b21d5f6af702590
 Author: Keith Packard <keithp@keithp.com>
 Date:   Thu Mar 13 21:30:18 2008 -0700

    Add funcs to convert between protocol and pixman matrices

 commit f547650328287545a7a4d96df8d6a6c606dd95a9
 Author: Keith Packard <keithp@keithp.com>
 Date:   Thu Mar 13 14:50:13 2008 -0700

    Export a bunch of matrix operations from render.

    The render extension uses many matrix operations internally, this change
    exposes those functions to other parts of the server, drivers and
    extensions. The change is motivated by the 'transform' additions to the
    RandR extension but will likely be useful elsewhere.
