As a good practice and for eventual double frees.
The reason of this patch is due the resilience of xf86XVInitAdaptors, where
for any adaptor failure it's able to keep trying registering the following
ones.
I discussed briefly with Pauli and Ville about a bigger refactoring of such
function, doing it in a way to return instantly when a failure happens; after
all that's how mostly of the other driver functions work. Instead, we just
thought that xf86XVInitAdaptors is wise and cool, and eventually other driver
functions should be even following the main idea of resilience.

When xf86XVFreeAdaptor is called more than once in xf86XVInitAdaptors (it may,
but not often), the conditional being changed in this patch will always take
true path and will keep freeing pAdaptor->pAttributes, thus letting the system
error-prone.
This patch fix such problem checking for a pointer instead the number of
attributes. Such pointer will be deallocated when xf86XVFreeAdaptor is called
first and will not let the code re-run in the following calls. This is a bit
similar how the surroundings code is already doing.

If window gets exposed but clipboxes doesn't change drivers would avoid

background is painted.
To help drivers to avoid filling colorkey for each put server can
provide helper function if there is exposed areas. Server can subtract
exposed areas from filled region.
As a side effect we can avoid useless color key fills if window only
moves in screen without background fills.

PutImage/PutStill respect the GC clip, however ReputImage does not.
PutImage/PutStill are supposed to be oneshot operations so ReputImage
should never expand the area covered by the clip, instead it should

This is a combination of a huge mechanical patch and a few small
fixups required to finish the job. They were reviewed separately, but
because the server does not build without both pieces, I've merged
them together at this time.
The mechanical changes were performed by running the included
'fix-region' script over the whole tree:
$ git ls-files | grep -v '^fix-' | xargs ./fix-region
And then, the white space errors in the resulting patch were fixed
using the provided fix-patch-whitespace script.
$ sh ./fix-patch-whitespace
Thanks to Jamey Sharp for the mighty fine sed-generating sed script.
The hand-done changes involve removing functions from dix/region.c
that duplicate inline functions in include/regionstr.h, along with
their declarations in regionstr.h, mi.h and mispans.h.

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.

Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.
This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)
LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.
xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).
This is the biggest "visibility" patch. Instead of doing a "export"
symbol on demand, export everything in the sdk, so that if some module
fails due to an unresolved symbol, it is because it is using a symbol
not in the sdk.
Most exported symbols shouldn't really be made visible, neither
advertised in the sdk, as they are only used by a single shared object.

This patch exports all symbols required by the compilable
(in a x86 linux computer) xorg/driver/* modules.

fbShmPutImage no longer available (and should have been static)
mga
MGAGetClientPointer (should come from matrox's libhal)
This is not a definitive "visibility" patch, as all it does is to
export missing symbols, but the modules that current don't compile,
may require more symbols once fixed, and third party drivers should
also require more symbols exported.
A "definitive" patch should export symbols defined in the sdk.
over to new system.
Need to update documentation and address some remaining vestiges of
old system such as CursorRec structure, fb "offman" structure, and
FontRec privates.
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.
This allows overlay Xv adaptors to work slightly better with compositing
managers.
Bump the video driver ABI minor so drivers only need to check for this at build
time.
Get rid of almost all uses of these definitions. They're still defined for
delinquent out-of-tree drivers, and also for the Mesa build. As well as
for miinitext.c. But largely gone.
