- fbChangeWindowAttributes can create pixmaps (and access them) without use preparing access.
- Also handle the destroyed pixmaps by finishing them first.
- Switch to DEST indices again in exaCreatePixmapWithPrepare, because they are obviously being rendered to.
- Also avoid calling FinishAccess on pixmaps that are destroyed (and their memory potentially invalid).
- In a previous patch i forgot to add a FALSE somewhere it seems.
- Rename AUX indices so the driver (think of driver managed pixmaps) can do optimisations based upon them.
- Fix one abuse of DEST index now that we have the AUX indices (same reason as above).
Preserve the EXA ABI by introducing a new driver flag EXA_SUPPORTS_PREPARE_AUX.
If the driver doesn't set this flag, we have to assume any Prepare/FinishAccess
driver hooks can't handle the EXA_PREPARE_AUX* indices, so we move out such
pixmaps at PrepareAccess time.

- The src optimisation is more aggressive and possibly harmful in light of the new initial state of pixmaps.
- There is now actually a performance improvement by almost always keeping the number of rects low.
- use DEST in the createPixmap wrapper, because stipple already takes MASK (in case someone uses swappers).
- Anticipate some of the less common situations when fbValidateDrawable will access tile related pixmaps.
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.
Symbols in the sdk (or referenced in sdk macros), but not defined
anywhere include:

This patch exports all symbols required by the compilable
(in a x86 linux computer) xorg/driver/* modules.
Still missing symbols worth mentioning are:
sunleo
miFindMaxBand no longer available
intel (uxa/uxa-accel.c)
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.
- Redo damage naming for more consistency.
- Call post submission functions only where appropriate.
- EXA can now live without it's odd damage workarounds.
There's no reason to not just dispatch this straight into the GC. As a
bonus, if you do so, damage wraps correctly, and thus swcursor works.
The side effect is it's no longer possible to override ShmPutImage with
ShmRegisterFuncs().
Also remove the (broken) damage tracking for same from EXA, since it didn't
work right, and is now superfluous.
It's buggy without Composite acceleration (leading to cropped glyphs) and not
really useful in that case anyway. The bug probably still needs to be found and
fixed for drivers that provide a PrepareComposite hook but can't accelerate
text rendering though.
Recording damage from other operations (e.g. creating a client damage record)
may confuse the migration code resulting in corruption.
Option "EXAOptimizeMigration" appears safe now, so enable it by default. Also
remove it from the manpage, as it should only be necessary on request in the
course of bug report diagnostics anymore.
Add back exaGlyphs(); the new version copies the glyph images
onto a single large glyph pixmap and draws from their to the
destination surface. This reduces the management of small
offscreen areas and will allow us to avoid texture unit setup
between each glyph.
These hints allow an acceleration architecture to optimize allocation of certain
types of pixmaps, such as pixmaps that will serve as backing pixmaps for
redirected windows.
