When an RandR shared pixmap is created in rrCreateSharedPixmap, it has a refcnt
of 1. Then, PixmapShareToSlave bumps the refcnt to 2. However, there's no
corresponding PixmapUnshareFromSlave where the refcnt can be decreased again,
and there's no convenient common place where the refcnt can be decremented when
the slave pixmap is destroyed.
Fix this by just unreffing the pixmap twice in RRCrtcDetachScanoutPixmap.

to keep it updated from the current front pixmap.
If the resize means the crtc is no longer used it will destroy

This patch makes the former's logic equivalent to the latter's which allows

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:

pixman 0.13.2 now holds all of the matrix operations. This leaves
the protocol conversion routines and some ABI stubs in place
Signed-off-by: Keith Packard <keithp@keithp.com>
Dereferencing the NULL mode pointer would cause a crash. As these transform
matrices won't be used while the CRTC is disabled, just leave their values
alone.
Instead of using a separate function to notify DIX about transform changes,
add the transform to RRCrtcNotify so that the whole Crtc state changes
atomically.
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.
Add APIs to xf86RandR12 support and randr extension to record whether the
driver supports transforms, report that value in the RRGetCrtcTransform
reply.
It doesn't make sense to have the client invert this matrix when the server
can do so reasonably efficiently. This avoids weird fixed point rounding
errors when testing the transform against its inverse. Now to fix the
protocol.
New RRCrtcGetTransform function in DIX that DDX can use to get the pending
transform. The DDX code should be complete; the DIX code is just a stub at
this point.
Upon recreation of the RandR internal data structures in RRCrtcNotify() the
crtc of an output could be NULLed if the crtc was shared (cloned) between two
outputs and one of them got another crtc assigned.
Set the new randr crtc of the output before the output change notification is
delivered to the clients.
Remove RROutputSetCrtc as it is not really necessary. All we have to do is set
the output's crtc on RRCrtcNotify
When checking how to validate the selected mode and position against the
current screen size, the test against 90/270 rotation did not mask out
reflection, so that when reflection was specified, the 90/270 test would
never succeed. This caused incorrect bounds checking and would return
an error to the user instead of rotating the screen.
Yes, two changes in one commit. Sorry 'bout that.
The first change ensures that when pending property values have been
changed, a mode set to the current mode will actually do something, rather
than being identified as a no-op. In addition, the driver no longer needs to
manage the migration of pending to current values, that is handled both
within the xf86 mode setting code (to deal with non-RandR changes) as well
as within the RandR extension itself.
The second change eliminates the two-call Create/AttachScreen stuff that was
done in a failed attempt to create RandR resources before the screen
structures were allocated. Merging these back into the Create function is
cleaner.

I think master and server-1.3-branch are more in sync now.
RRModes are referenced by the resource db, RROutput and RRCrtc structures.
Ensure that the mode reference count is decremented each time a reference is
lost from one of these sources. The missing destroys were in
RRCrtcDestroyResource and RROutputDestroyResource, which only happen at
server reset time, so modes would be unavailable in subsequent server
generations.
The RandR protocol spec has several requests in support of user-defined
modes, but the implementation was stubbed out inside the X server. Fill out
the DIX portion and start on the xf86 DDX portion. It might be necessary to
add more code to the DDX to insert the user-defined modes into the output
mode list.

xf86 drivers need to create RandR object in the PreInit stage,
before the ScreenRec is allocated. Changing the RandR DIX code
to permit this required the addition of functions that later associate the
objects with the related screen.
An additional change is that modes are now global, and no longer associated
with a specific screen. This change actually makes mode management cleaner
as there is no more per-screen list of modes to deal with.
This changes the RandR 1.2 ABI/API for drivers.
