The logical size is the size of the output in the global compositor
space. The mode width/height should be scaled as in the logical
size, but shouldn't be transformed. Thus we need to rotate back
the logical size to be able to use it as the mode width/height.
This fixes issues with pointer input on transformed outputs.

When xdg_output support was added to Xwayland, need_rotate parameter was
added to output_get_new_size where true gave you the old pre-xdg_output
behavior and false gave the new behavior. Unfortunately, the two places
where this is called, need_rotate was set backwards. This caused input
get clampped to the wrong dimensions. Also, the logic for deciding
whether or not to flip was wrong because, if need_rotate was false, it
would always flip which is not what you want.

The xdg-output protocol aims at describing outputs in way which is
more in line with the concept of an output on desktop oriented systems.
For now it just features the position and logical size which describe
the output position and size in the global compositor space.
This is however much useful for Xwayland to advertise the output size
and position to X11 clients which need this to configure their surfaces
in the global compositor space as the compositor may apply a different
scale from what is advertised by the output scaling property (to achieve
fractional scaling, for example).
This was added in wayland-protocols 1.10.

Previously, we would swap the width/height of the Xwayland output based
on the output rotation, so that the overall screen size would match the
actual rotation of each output.
Problem is the RandR's ConstrainCursorHarder() handler will also apply
the output rotation, meaning that when the output is rotated, the
pointer will be constrained within the wrong dimension.
Moreover, XRandR assumes the original output width/height are unchanged
when the output is rotated, so by changing the Xwayland output width and
height based on rotation, Xwayland causes XRandr to report the wrong
output sizes (an output of size 1024x768 rotated left or right should
remain 1024x768, not 768x1024).
So to avoid this issue and keep things consistent between Wayland and
Xwayland outputs, leave the actual width/height unchanged but apply the
rotation when computing the screen size. This fixes both the output size
being wrong in "xrandr -q" and the pointer being constrained in the
wrong dimension with rotated with weston.

If the Wayland compositor sets a rotation on the output, Xwayland
translates the transformation as an xrandr rotation for the given

However, if the rotation is not supported by the CRTC, this is not
a valid setup and xrandr queries will fail.
Pretend we support all rotations and reflections so that the
configuration remains a valid xrandr setup.

216bdbc735 removed the SetRootClip call in the XWayland output-hotplug
handler when running rootless (e.g. as a part of Weston/Mutter), since
the root window has no storage, so generating exposures will result in
writes to invalid memory.
Unfortunately, preventing the segfault also breaks sprite confinement.
SetRootClip updates winSize and borderSize for the root window, which
when combined with RRScreenSizeChanged calling ScreenRestructured,
generates a new sprite-confinment area to update it to the whole screen.
Removing this call results in the window geometry being reported
correctly, but winSize/borderSize never changing from their values at
startup, i.e. out of sync with the root window geometry / screen
information in the connection info / XRandR.
This patch introduces a hybrid mode, where we update winSize and
borderSize for the root window, enabling sprite confinement to work
correctly, but keep the clip emptied so exposures are never generated.

Started out as an Xorg module to be used from Xorg drivers to let
Xorg run under a wayland server. The idea was to be able to reuse the
2D acceleration from the Xorg driver. Now with glamor being credible,
a better plan is to just make Xwayland its own DDX, similar to Xwin
and Xquartz. This is a much better fit, as much of the code in the
original approach had to hack around Xorg doing Xorg things like take
over the VT, probe input devices and read config files. Another big win
is that Xwayland dosn't need to be setuid root.
The Xwayland support for DRI3, Glamor and render nodes was done by
Axel Davy <axel.davy@ens.fr>, who also did a lot of work on the rebase
to the Xwayland DDX.
