While we now have support for resize of the root window through

The upcoming handling of plain xdg_toplevel.configure events will need

When handling libdecor configure, we first update our xwl output and
screen if dimensions differ from the current xwl_screen, and then commit
a new libdecor frame which acknowledges the xdg_surface.configure event.
If the initial configure events contains non-zero dimensions, we will
update the xwl output before acknowledging the initial configure. As we
attach a buffer and commit the surface when updating the output, this
leads to a protocol error.
Instead, move the surface commit till the end of the configure handler
so it always happens after the ack.

The configure handler in libdecor is triggered any time a new
configuration is received.
According to the documentation from libdecor, an application should
respond to that event by creating a suitable libdecor_state, and apply
it using libdecor_frame_commit().
So we ought to attach a new buffer matching the new size and commit
the Wayland surface.
The actual content of the window does not need to be explicitly
repainted, that occurs through the call to SetRootClip():
xwl_output_set_mode_fixed()
-> update_screen_size()
-> SetRootClip()
-> miHandleValidateExposures()
-> miWindowExposures()
-> miPaintWindow()

Note: All Xservers are actually affected by this issue, but with most
regular X servers, the compositing manager will take care of dealing

One general assumption in Xwayland is that the xwl_window remains the
same for all the child windows of the toplevel window.
When mapping a new X11 window, ensure_surface_for_window() checks for an
existing xwl_window by using xwl_window_get() which will just check for
the registered xwl_window for the window.
That means that a client mapping a child window of an existing window
with a xwl_window will get another different xwl_window.
If an X11 client issues a Present request on the parent window, hence
placed underneath its child window of the same size, the Wayland
compositor may not send the frame callback event for the parent's
Wayland surface which is reckoned to be not visible, obscured behind
the other Wayland surface for the child X11 window.
That bug affects some games running in wine which may get 1 fps because
the repaint occurs only on timeout with a long interval (as with, e.g.

For window-manager managed windows, xwl_realize_window is only called for

Usualy this is not a problem since we walk all client windows to update

But for apps which first do the randr change and only then create their

That is for example the case for KWin, which reparents client windows to one
decoration and another wrapper parent window.
Account for that by a recursion into the tree. For now assume as before that
all X11 window managers reparent with one child only for these parent windows.
Changes by Hans de Goede:
- Move the xwl_window_is_toplevel() from a later patch in this series here
as it really belongs together with these changes
- Drop no longer necessary xwl_window argument from window_get_none_wm_owner
parameters

When a viewport is already created we can reuse this object instead of
destroying it and getting a new one for updating the source rectangle and
destination size.

Instead of iterating over all clients which are listening for events on the
root window and checking if the client we are dealing with is the one
listening for SubstructureRedirectMask | ResizeRedirectMask events and thus
is the window-manager, cache the client-id of the window-manager in
xwl_screen and use that when checking if a client is the window-manager.
Note that we cache and compare the client-id rather then the ClienPtr,
this saves reading the ClientPtr from the global clients array when doing
the comparison.

The first phase sets the new surface properties for all damaged
windows, then the second phase commits all surface updates.
This is preparatory for the next change, there should be no observable
change in behaviour (other than the order of Wayland protocol
requests).

Now that each source and header should be in order, we can safely cleaup
the last remaining bits from the main `xwayland.h` which is not needed
anymore and can be removed.

Over time, Xwayland main source file `xwayland.c` has grown in size
which makes it look cluttered and harder to read.
Move the code dealing with Xwayland window to its own source and header
files.
