This is to avoid issues with redirected windows which are located partly or
fully outside of a screen edge, resulting in unusual cliprects which the 3D
drivers generally can't handle. The symptoms in such cases would be incorrect
rendering or even crashes or hangs.
at server startup, and not against the virtual X/Y parameters
as they can change.
This fixes an issue when canGrow is TRUE and modes get dropped
when using the virtual X/Y parameters.
Xprt links libfb, which now uses pixman. Update configure.ac to
require module $PIXMAN for XPRINT.
Also, use $(top_builddir) to reference libfb.la and other local
libraries, rather than using the relative reference ../..
Major stylistic cleanups, greatly expanded cross-reference ("SEE ALSO")
section and some typo fixes.

When the root window changed size, xf86XVFillKeyHelper would not revalidate
the GC, leaving the clip at the old size causing lossage (and possibly
memory corruption if the screen and frame buffer shrank).
Fixed by just using a scratch GC; saving memory, eliminating bugs and
shrinking the code.
To be used by AIGLX for GLX_EXT_texture_from_pixmap without several data copies.
The texOffsetStart hook must make sure that the given pixmap is accessible by
the GPU for texturing and return an 'offset' that can be used by the 3D
driver for that purpose.
The texOffsetFinish hook is called when the pixmap is no longer being used for
texturing.
DRI uses a non-screen block/wakeup handler which will be executed after the
screen block handler finishes. To ensure that the rotation block handler is
executed under the DRI lock, dynamically wrap the screen block handler for
rotation.
Leaving devices enabled during server startup can cause problems during the
initial mode setting in the server, especially when they are used for
different purposes by the X server than by the BIOS. Disabling all of them
before any mode setting is attempted provides a stable base upon which the
remaining mode setting operations can be built.
The code in hw/xfree86/os-support/bus/sparcPci.c:simbaCheckBus()
is trying to mimmick VGA routing by disabling I/O space responses
behind the Simba PCI-PCI controller.
Unfortunately, doing this also happens to disable access to the
IDE controller I/O space registers, thus crashing the system. The
granularity of the I/O disabling in the Simba controller is not
fine enough to disable VGA without also disabling the IDE controller
registers.
When the modules section is parsed, if a module is set to be loaded by
default, this will be logged. If it is redundantly specified in xorg.conf,
this will also be noted. None of this logging will happen if the xorg.conf
lacks a modules section.
This provides a new option, UseDefaultFontPath. This option is enabled by
default, and causes the X server to always append the default font path
(defined at compile time) to the font path for the server. This will allow
people to specify additional font paths if they want without breaking
their font path, thus hopefully avoiding ye olde "fixed front" problem.
Because this option is a ServerFlag option, the ServerFlags need to be
processed before the files section of the config file, so swap the order
that they are processed.
Provide default modules that may be overrided easily. Previously the
server would load a set of default modules, but only if none were
specified in the xorg.conf, or if you didn't have a xorg.conf at all. This
patch provides a default set and you can add only the "Load" instructions
to xorg.conf that you want without losing the defaults. Similarly, if you
don't want to load a module that's loaded by default, you can add "Disable
modulename" to your xorg.conf (see man xorg.conf in this release for
details). This allows for a minimal "Modules" section, where the user only
need specify what they want to be different. See bug #10541 for more.
The list of default modules is taken from the set loaded by default when
there was a xorg.conf containing no "Modules" section.
A potential problem for some users is that some users disable a module,
most notably DRI, by commenting out the "Load" line in their xorg.conf.
This needs to be changed to an uncommented "Disable" line, as DRI is
loaded by default.
