Seeing as this code seems to be specific to OpenBSD I don't think
__x86_64__ should have been added there at all. It appears to have
been added wherever __amd64__ existed before which is wrong. I
think that part of the commit should be reverted but also all four of
the checks should be __OpenBSD__ && __amd64__ instead of two one
direction and two flipped.
The first guess used to be "is the preferred mode for one output the
preferred mode on all outputs". Instead, do "find the largest mode that's
preferred for at least one output and available on all outputs".
Old logic was just the first one that happened to have an associated
CRTC. The new logic tries to find one that's definitely connected, has
probed modes, and has the largest candidate mode.
Most of these drivers didn't work. ati was the only one that even came
close. The igs, ipaq, itsy, pcmcia, savage, sis530, trident, trio, ts300,
and vxworks directories have never built since modularisation, so clearly
no one can miss them.
Create a new exported global variable, XineramaVisualsEqualPtr. Use this
pointer to decide whether two visuals are equal during visual consolidation.
This pointer can be wrapped, which allows drivers and extensions to control
which visuals are consolidated. A wrapper can reject the visuals without
calling down, but must call down and return that result if it deems the visuals
equal. This ensures that all layers agree that the visuals are equal.
Pass the screen of the other visual into the VisualsEqual callchain.
Don't free PanoramiXVisuals since we need it for PanoramiXTranslateVisualID.
Don't skip the first visual on the other screen in PanoramiXMaybeAddVisual.
Skip the loop in PanoramiXTranslateVisualID if screen is 0.
The -wm (when mapped) option for the BackingStore support has been
causing the server to dereference a NULL pointer.
This has probably been the case since backing store has been
implemented on top of Composite.
It looks like (some of?) Composite didn’t expect its WIndowPtr
argument to be the root window.
In Composite’s compCheckRedirect() function we now avoid calling
compAllocPixmap() and compFreePixmap() when the pWin pointer’s
parent member is NULL, as is it the case with a server’s root window.
This addresses:

KdInitOutput() used to enable Composite when it was disabled by default,
but now this hack prevents ``-extension Composite'' from working.
Remove it, as Composite is enabled by default anyway.
Use dummy config functions to replace those from config/config.c, and
therefore do not link Xprt with $CONFIG_LIB.
Works around an endlessly spinning loop in dix/dispatch.c::Dispatch()
(WaitForSomething() not waiting) when built with dbus, which was
causing Xprt to use 95% cpu.
