5cb5bdf1bc Add gdk_display_get_toplevel_windows
This is replacing the corresponding GdkScreen api, which

43c212ac28 build: Enable -Wswitch-enum and -Wswitch-default
This patch makes that work using 1 of 2 options:

1. Add all missing enums to the switch statement
  or
2. Cast the switch argument to a uint to avoid having to do that (mostly
   for GdkEventType).

I even found a bug while doing that: clearing a GtkImage with a surface
did not notify thae surface property.

The reason for enabling this flag even though it is tedious at times is
that it is very useful when adding values to an enum, because it makes
GTK immediately warn about all the switch statements where this enum is
relevant.
And I expect changes to enums to be frequent during the GTK4 development
cycle.

0bdaebef1e window: Improve detection of edge constraint support
Instead of relying on special values of edge constraints, this
patch adds an internal-only gdk_window_supports_edge_constraints()
function that by default returns FALSE, and is implemented by
GdkWindowWayland and GdkWindowX11.

This way, we can properly detect server-side support for this
feature and adapt accordingly.

d54117024c x11: Add call to XInitThreads()
The Mesa Vulkan drivers need XInitThreads() being called, because their
implementation has to use threads.

And I don't want to make the call depend on if Vulkan is compiled in
because that makes GTK's X11 behavior depend on compile-time flags, so
it's always called.

4a6f8a065a gdk: remove the display->list_devices vfunc
gdk_display_list_devices is deprecated and all the backends
implement the same fallback by delegating to the device manager
and caching the list (caching it is needed since the method does
not transfer ownership of the container).

initialize the list lazily only in the case someone calls the
deprecated method.

0d109867d2 Tweak startup-notification after the first window
Presently, Gtk will only send a startup notification completion message
for the first window that is shown.  This is not good for the case of
GtkApplication, where we are expected to participate in
startup-notification for all windows.

We have avoided this problem by manually emitting the startup complete
message from after_emit in GtkApplication.

Unfortunately, this causes problems for windows that are shown with a
delay.  It is also a dirty hack.

The reason for the original behaviour is simple: there is a static
boolean in gtkwindow.c which controls it.  We remove this.

Instead, clear the startup notification ID stored in GDK when sending
the completion message.  GtkApplication will re-set this the next time
an event comes in which needs startup-notification handling.  In the
non-GtkApplication case, newly shown windows will still not send the
message, since the cookie will have been cleared.

Finally, we remove the hack from GtkApplication's after_emit.

This will probably cause some regressions in terms of lingering startup
notification messages.  The correct solution here is to always use
gtk_window_present(), including when merely opening a new document (with
a new tab, for example).

55edc81c10 x11: Make selection handling work across screens
When dealing with selection events, we might see windows from
other screens in the requestor field. The current x11 backend
code fails to wrap these in a foreign GdkWindow, since we
don't have the corresponding GdkScreen anymore. Work around
this by creating such 'foreign screens' on demand. We still
maintain the 1:1 relation between the display and the screen
returned by gdk_display_get_default_screen().

6504b2e534 GdkDisplayX11: Properly translate server timestamps from _NET_WM_FRAME_* messages
When using frame times from _NET_WM_FRAME_DRAWN and _NET_WM_FRAME_TIMINGS, we
were treating them as local monotonic times, but they are actually extended-precision
versions of the server time, and need to be translated to monotonic times in the
case where the X server and client aren't running on the same system.

a00a5ed210 GtkApplication: avoid using stale timestamps
Avoid using a stale timestamp (from the last user interaction with the
application) when a message arrives from D-Bus requesting that a new
window be created.

In this case the most-correct thing that we can do is to use no
timestamp at all.

We modify gdk_x11_display_set_startup_notification_id() to allow a NULL
value to mean "reset everything" and then call this function
unconditionally on receipt of D-Bus activation requests.  The result
will be that a missing desktop-startup-id in the platform-data struct
will reset the timestamp.

Under their default configuration metacity and mutter will both map
windows presented with no timestamp in the foreground.  This could
result in false-positive, but there is very little we can do about that
without the original timestamp from the user event.

e670720d19 gtk3: add randr 1.5 monitor support
This patch introduces support for using the newly introduced
monitor objects in the XRandR protocol. These objects are meant
to be used to denote a set of rectangles representing a logical
monitor, and are used to hide details like monitor tiling and
virtual gpu outputs.

This uses the new objects instead of crtc/outputs objects when
they are available to create the monitor lists. X server 1.18
is required on the server side for randr 1.5.

608c25453b x11: round the scaled size *up* when we get a ConfigureNotify
Although we specify a resize increment to try and get a size that is
a multiple of the window scale, maximization typically wins
over the resize increment, so the window might be odd sized.

Round *up* in this case, rather than down, since it's better to
truncate a line or two at the bottom and right of the window rather
than have a line or two that we don't know what to do with.

038aac6275 gdk: Add support for OpenGL
This adds the new type GdkGLContext that wraps an OpenGL context for a
particular native window. It also adds support for the gdk paint
machinery to use OpenGL to draw everything. As soon as anyone creates
a GL context for a native window we create a "paint context" for that
GdkWindow and switch to using GL for painting it.

This commit contains only an implementation for X11 (using GLX).

The way painting works is that all client gl contexts draw into
offscreen buffers rather than directly to the back buffer, and the
way something gets onto the window is by using gdk_cairo_draw_from_gl()
to draw part of that buffer onto the draw cairo context.

As a fallback (if we're doing redirected drawing or some effect like a
cairo_push_group()) we read back the gl buffer into memory and composite
using cairo. This means that GL rendering works in all cases, including
rendering to a PDF. However, this is not particularly fast.

In the *typical* case, where we're drawing directly to the window in
the regular paint loop we hit the fast path. The fast path uses opengl
to draw the buffer to the window back buffer, either by blitting or
texturing. Then we track the region that was drawn, and when the draw
ends we paint the normal cairo surface to the window (using
texture-from-pixmap in the X11 case, or texture from cairo image
otherwise) in the regions where there is no gl painted.

There are some complexities wrt layering of gl and cairo areas though:
* We track via gdk_window_mark_paint_from_clip() whenever gtk is
  painting over a region we previously rendered with opengl
  (flushed_region). This area (needs_blend_region) is blended
  rather than copied at the end of the frame.
* If we're drawing a gl texture with alpha we first copy the current
  cairo_surface inside the target region to the back buffer before
  we blend over it.

These two operations allow us full stacking of transparent gl and cairo
regions.

99ac2f5c49 Fix font size when gdk_x11_display_set_window_scale() is used
We have a hack in the XSETTINGS code to substitute gtk-xft-dpi
with gdk-unscaled-dpi unless the screen has a fixed window scale,
in which case we just use gtk-xft-dpi.

But if the screen is changed to have a fixed window scale, then
the substituted value of gdk-unscaled-dpi will stick around until
the next (coincidental) change to XSETTINGS. To fix this, force
an immediate reread of the XSETTINGS property when
gdk_x11_display_set_window_scale() is used.

bb11195ec0 GdkFrameClock: Clean up the public API
* remove gdk_frame_clock_get_frame_time_val(); a convenience
  function that would rarely be used.
* remove gdk_frame_clock_get_requested() and
  ::frame-requested signal; while we might want to eventually
   be able to track the requested phases for a clock, we don't
  have a current use case.
* Make gdk_frame_clock_freeze/thaw() private: they are only
  used within GTK+ and have complex semantics.
* Remove gdk_frame_clock_get_last_complete(). Another convenience
  function that I don't have a current use case for.
* Rename:
  gdk_frame_clock_get_start() => gdk_frame_clock_get_history_start()
  gdk_frame_clocK_get_current_frame_timings() => gdk_frame_clock_get_timings()

fb44ea8a85 Add gdk_frame_timings_get_predicted_presentation_time()
For an operation like synchronizing audio to video playback, we need to
be able to predict the time that a frame will be presented. The details
of this depend on the windowing system, so make the backend predict
a presentation time for ::begin-frame and set it on the GdkFrameTimings.

The timing algorithm of GdkFrameClockIdle is adjusted to give predictable
presentation times for frames that are not throttled by the windowing
system.

Helper functions:

 gdk_frame_clock_get_current_frame_timings()
 gdk_frame_clock_get_refresh_info()

are added for operations that would otherwise be needed multiple times
in different locations.

In order to be able to track statistics about how well we are drawing,
and in order to be able to do sophisticated things with frame timing
like predicting per-frame latencies and synchronizing audio with video,
we need to be able to track exactly when previous frames were drawn
to the screen.

Information about each frame is stored in a new GdkFrameTimings object.
A new GdkFrameHistory object is added which keeps a queue of recent
GdkFrameTimings (this is added to avoid further complicating the
implementation of GdkFrameClock.)

355e305c16 Freeze the update counter for unmapped windows
When a window is unmapped, freeze its frame clock. This avoids doing

frame ended while the window was withdrawn.

8a6895fe52 Use _NET_WM_FRAME_DRAWN to synchronize frame drawing
As part of the extended _NET_WM_SYNC_REQUEST_COUNTER protocol,
we get a _NET_WM_FRAME_DRAWN message for each frame we draw. Use this
to synchronize the updates we are doing with the compositing manager's
drawing, and ultimately with with display refresh.

We now set the sync request counters on all windows, including
override-redirect windows, since it is also useful to do synchronized,
atomic updates for such windows.

69f457426a Switch to an extended form of _NET_WM_SYNC_REQUEST_COUNTER
By exporting two XSync counters on a toplevel window, we subscribe
to an extended form of the _NET_WM_SYNC_REQUEST_COUNTER protocol,
where the window manager can initiate an atomic frame, as previously,
but the application can also do so by incrementing the new counter to
an odd value, and then to an even value to finish the frame.

See:
https://mail.gnome.org/archives/wm-spec-list/2011-October/msg00006.html

The support for 64-bit integers that GLib requires is used to
simplify the logic.

001f960a43 GdkDisplayX11: Don't use substructure events in internal accounting
We may receive events because SubstructureNotifyMask has been selected
for the root window. (Most likely, this would occur because GTK+
is being used inside a window manager like Metacity or Mutter.)
This can confuse various types of internal accounting, so detect
such events and comprehensively ignore them for GDK's internal
purposes. We still need to generate GDK events for these cases
because you can select for substructure events with
GDK_SUBSTRUCTURE_MASK.
