Both `gbm_bo_create()` and `gbm_bo_create_with_modifiers()` can fail and
return `NULL`.
If that occurs, `xwl_glamor_gbm_create_pixmap()` will not create a
pixmap for the (NULL) GBM bo, but would still try to free the bo which
leads to a crash in mesa:

To avoid the crash, only free the GBM bo if not `NULL`.

Set a linear gamma ramp. This avoids the xrandr command always warning
'Failed to get size of gamma for output default'
(perhaps we should be using GDI GetDeviceGammaRamp(), if possible?)
Make CRTC report non-zero physical dimensions initially
The rrGetInfo hook is not called for all RANDR requests (e.g.
RRGetOutputInfo), so we must always keep the fake mode information up to
date, rather than doing it lazily in the rrGetInfo hook)
Because we are so bad, most GTK+3 versions treat the output name 'default'
specially, and don't try to use RANDR with it. But versions 3.21.6 to
3.22.24, don't do this, and get badly confused by a CRTC with size 0x0.
See:

Make QueryMonitor() slightly less insane, making it return TRUE if the

return errors, see 5940580f)
Also: Spamming the long UseMsg() after "Invalid monitor number" isn't very
helpful.
Also: If we are exiting in ddxProcessArgument() due to an error in
options, use a non-zero exit status.
The PresentOptionSuboptimal support code is not optional (once you've

Suppose you're in a Hyper-V guest and are trying to use PCI passthrough.
The ID_PATH that udev will construct for that looks something like
"acpi-VMBUS:00-pci-b8c8:00:00.0", and obviously looking for "pci-" in
the first four characters of that is going to not work.
Instead, strstr. I suppose it's possible you could have _multiple_ PCI
buses in the path, in which case you'd want strrstr, if that were a
thing.
Using the existing command line option "-listen" for passing file
descriptors between the Wayland compositor and Xwayland is misleading,
Xwayland should add is own command line option for that specific use.
As XWayland is spawned by the Wayland compositor, we cannot just change
the option, as that would break all existing Wayland compositors using
Xwayland, so we add a new options "-listenfd" and mark the previous one
as deprecated and log a warning, but it still works for backward
compatibility.

Xwayland uses the command line option “-listen” to pass file descriptors
from the Wayland compositor.
That breaks the traditional, documented behavior of the “-listen”
command line option which is to enable a transport type.
Checks if the given option starts with a digit, otherwise treat it as a
regular transport type.

a2rgb10 configs would end up with channel masks corresponding to
argb8888. This would confuse the GLX core code into matching an a2rgb10
config to the root window visual, and that would make things look wrong
and bad.
Fix this by handling more cases. We're still not fully general here, and
this could still be wrong on big-endian. The XXX comment about doing
something less ugly still applies, ideally we would get this information
out of EGL instead of making lucky guesses. Still, better than it was.

Add an option to turn on the use of the X window's alpha channel in
multiwindow mode, i.e. this uses the X window's alpha channel for
compositing into the native desktop.
This works on W7/Vista (using DwmEnableBlurBehindWindow()), and Windows
10 (using the undocumented SetWindowCompositionAttribute()), but not on
Windows 8/8.1
-compositewm must be enabled for this to be useful, as we only have a
pixmap with an alpha channel for the X window in that case. The
framebuffer/root window doesn't have one (unless perhaps you are using
the rootless extension, maybe...).
v2:
Update meson.build
Future work:
A window property to control use of alpha?
Option to turn off blur on W7/Vista
Implement _NET_WM_WINDOW_OPACITY
I think that a major cost in the current implementation is doing a
CreateDIBSection()/DestroyObject() on every refresh. So provide our own

Push the multiwindow wndproc WM_PAINT handling down into the drawing

so we only need to do this in the GDI engine.
Make winBltExposedRegionsShadowGDI() do the same stuff that
winTopLevelWindowProc()'s WM_PAINT handler does.
Note that winBltExposedRegionsShadowGDI() is currently used 1) in
windowed mode when the GDI engine is selected, and 2) in multiwindow
mode when "Hide Root Window" is off.
We can't have high keycodes because everything in XKB relies on 8 bits. XI2's
API allows for 32-bit keycodes so we have to take those but nothing in the

keycode grab is clipped to 255 and thus ends up grabbing a different key
instead.

Desktop GL can handle arbitrary rops here, GLES can't. The switch
statement attempts to optimize some cases that GLES can still handle if
we precompute the right pixel value, but we were then throwing that
pixel value away and using gc->fgPixel anyway. Fix this, and now
xts-render passes against glamor+gles.
Without this we're using driswrast to set up GLX visuals. This is
unfortunate because llvmpipe does not expose multisample configs, so
various apps that expect them will fail. With this we just query the
capabilities of the EGL that's backing glamor, and reflect that to the
GLX clients. This also paves the way for xserver to stop being a DRI
driver loader, which is nice.

On pointer enter notification, Xwayland checks for an existing pointer
warp with a `NULL` sprite.
In turn, `xwl_pointer_warp_emulator_maybe_lock()` checks for an existing
grab and the destination window using `XYToWindow()` which does not
check for the actual sprite not being `NULL`.
So, in some cases, when the pointer enters the surface and there is an
existing X11 grab which is not an ownerEvents grab, Xwayland would crash
trying to dereference the `NULL` sprite pointer:
