Currently, when a X11 client (usually the X11 window manager from a
Wayland compositor) changes the value of the X11 property
`_XWAYLAND_ALLOW_COMMITS` from `false` to `true`, all pending frame
callbacks on the window are discarded so that the commit occurs
immediately.
Weston uses that mechanism to prevent the content of the window from
showing before it's ready when mapping the window initially, but
discarding the pending frame callbacks has no effect on the initial
mapping of the X11 window since at that point there cannot be any frame
callback on a surface which hasn't been committed yet anyway.
However, discarding pending frame callbacks can be problematic if we
were to use the same `_XWAYLAND_ALLOW_COMMITS` mechanism to prevent
damages to be posted before the X11 toplevel is updated completely
(including the window decorations from the X11 window manager).
Remove the portion of code discarding the pending frame callback,
Xwayland should always wait for a pending frame callback if there's one
before posting new damages.

During startup, the xfree86 DDX's InitOutput() calls PreInit for
protocol screens first, and then GPU screens. On teardown, dix_main()
calls CloseScreen in the reverse order: GPU screens first starting with
the last one and then working backwards, and then protocol screens also
in reverse order.
InitOutput() calls ScreenInit in the wrong order: for GPU screens first and then
for protocol screens. This causes a problem for drivers that have global state
that is tied to the first screen that calls ScreenInit.
Fix this by simply re-ordering the for loops to call PreInit for
protocol screens first and then for GPU screens second.
ms_present_get_crtc() returns an RRCrtcPtr, but derives it from a xf86CrtcPtr
found via ms_dri2_crtc_covering_drawable()=>ms_covering_crtc(). As a result, it
depends on all associated DIX ScreenRecs having an xf86CrtcConfigPtr DDX
private.
Some DIX ScreenRecs don't have an xf86CrtcConfigPtr DDX private, but do have an
rrScrPrivPtr DDX private. Given that we can derive all of the information we
need from RandR, we can support these screens by avoiding the use of xf86Crtc.
This change implements an RandR-based path for ms_present_get_crtc(), allowing
drawables to successfully fall back to syncing to the primary output, even if
the slave doesn't have an xf86CrtcConfigPtr DDX private.
Without this change, if a slave doesn't have an xf86CrtcConfigPtr DDX private,
drawables will fall back to 1 FPS if they overlap an output on that slave.

DIX ScreenRecs don't necessarily have an xf86CrtcConfigPtr DDX private.
ms_covering_crtc() assumes that they do, which can result in a segfault.
Update ms_covering_crtc() to check the XF86_CRTC_CONFIG_PTR() returned pointer
before dereferencing it. This will still mean that ms_covering_crtc() can't fall
back to the primary output when a drawable overlaps a slave output (going to the
1 FPS default instead), but it won't segfault.
Signed-off-by: Alex Goins <agoins@nvidia.com>
ms_covering_crtc() uses RRFirstOutput() to determine a primary output to fall
back to if a drawable is overlapping a slave output.
If the primary output is a slave output, RRFirstOutput() will return a slave
output even if passed a master ScreenPtr. ms_covering_crtc() dereferences the
output's devPrivate, which is invalid for non-modesetting outputs, and can
crash.
Changing RRFirstOutput() could have unintended side effects for other callers,
so this change replaces the call to RRFirstOutput() with ms_first_output().
ms_first_output() ignores the primary output if it doesn't match the given
ScreenPtr, choosing the first connected output instead.

When a pixmap is created with a backing FBO, the FBO should be cleared
to avoid rendering uninitialized memory. This could happen when the
pixmap is rendered without being filled in its entirety.
One example is when a top-level window without a background is
resized. The pixmap would be reallocated to prepare for more pixels,
but uninitialized memory would be rendered in the resize offset until
the client sends a frame that fills these additional pixels.
Another example is when a new top-level window is created without a
background. Uninitialized memory would be rendered after the pixmap is
allocated and before the client sends its first frame.
This issue is only apparent in OpenGL implementations that don't zero
the VRAM of allocated buffers by default, such as RadeonSI.

Apps using randr to change the resolution when going fullscreen, in
combination with _NET_WM_STATE_FULLSCREEN to tell the window-manager (WM)
to make their window fullscreen, expect the WM to give the fullscreen window
the size of the emulated resolution as would happen when run under Xorg (*).
We need the WM to emulate this behavior for these apps to work correctly,
with Xwaylands resolution change emulation. For the WM to emulate this,
it needs to know about the emulated resolution for the Windows owning
client for each monitor.
This commit adds a _XWAYLAND_RANDR_EMU_MONITOR_RECTS property, which
contains 4 Cardinals (32 bit integers) per monitor with resolution
emulation info. Window-managers can use this to get the emulated
resolution for the client and size the window correctly.
*) Since under Xorg the resolution will actually be changed and after that
going fullscreen through NET_WM_STATE_FULLSCREEN will size the window to
be equal to the new resolution.

Add support for per client randr-resolution change emulation using viewport,
for apps which want to change the resolution when going fullscreen.
Partly based on earlier work on this by Robert Mader <robert.mader@posteo.de>
Note SDL2 and SFML do not restore randr resolution when going from
fullscreen -> windowed, I believe this is caused by us still reporting the
desktop resolution when they query the resolution. This is not a problem
because when windowed the toplevel window size includes the window-decorations
so it never matches the emulated resolution.
One exception would be the window being resizable in Windowed mode and the
user resizing the window so that including decorations it matches the
emulated resolution *and* the window being at pos 0x0. But this is an
extreme corner case. Still I will submit patches upstream to SDL2
and SFML to always restore the desktop resolution under Xwayland,
disabling resolution emulation all together when going windowed.
