GTK+ now uses the gtk-xft-dpi setting directly.
Note: this commit only fixes the backends that
currently provide this setting. The win32 and
Quartz backends still need to be fixed.
Drop the screen argument from gdk_dnd_find_window_for_screen
and rename the function to gdk_dnd_find_window. The screen
argument does not add anything here since the drag context
is already tied to the display. Update all backends, and
update all callers.
We are not emitting these events anymore, so lets remove them
from the api. The GdkSettingAction enum is moved to xsettings-client.c
where its only use remains.
Epoxy 1.4 has new ad hoc API that we can use to check whether GLX is
available on the current system.
If we didn't use this API, we'd have to manually dlopen libGL (or its
equivalent on different OSes) and check if it had GLX symbols; since
Epoxy already does all of this internally, we can simply ask it instead.

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.
-Wint-conversion is important because it checks casts from ints to
pointers.
-Wdiscarded-qualifiers is important to catch cases where we don't
strings when we should.
The behavior where a touchpoint takes over the pointer position is
really backend dependent. Since this went away from the generic code,
implement it here.
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.

Following the previous patch, where edge constraints support
was added to the Wayland backend, this patch introduces the
necessary code to handle the _GTK_EDGE_CONSTRAINTS atom from
X11 backend.

Under X, we were not setting the right drag cursor initially,
because at current_action == action == 0, initially. Fix this
by explicitly using the right cursor when grabbing.
This property contains 5 integers, of which the last 2 respectively
contain the tool serial number and tool ID. We were only extracting the
first so far, but GdkDeviceTool also has API getters for the latter,
which remained 0.

Interpret NULL as "root window" here - we only have one
screen nowadays, so there is no choice involved, and this
will let us avoid dealing with the root window in the
fontend code.
Don't set the have_focused field of the window's toplevel to TRUE by
default and don't set the FOCUSED state in gdk_window_map. This a means
toplevel window's state is what the WM expects, and the FOCUSED state
will be set anyway when we map the window and receive a _NET_WM_STATE
message.
Wacom tablets often have a "pad" device which houses multiple buttons. At
present, these devices are incorrectly marked as GDK_SOURCE_PEN which can
cause problems for some software.

The common compiler and linker flags control, among other things, the
default visibility of symbols; without them, we leak symbols that ought
to be private.
We're mixing a lot of styles in the Meson build files. This is an
attempt at making everything slightly more consistent in terms of
whitespace and indentation.
This is how it's done in the autotools build. Also avoids problems
with multiple source files having the same name (gdkeventsource.c).
Also move broadway backend code into broadway subdir.
Otherwise we wait for the next gdk_drag_motion() call, which will
happen on the next motion event, making the drag window briefly visible
on the 0,0 root coordinates.

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.
We're not currently using this, and dropping it allows us to loose
a bunch of code which leads us towards the goal of having GdkWindow
only for toplevels (and reparenting makes not sense for toplevels).
We can't really support these on e.g. wayland anyway, and we're trying
to get rid of subwindow at totally in the long term, so lets drop this.
It allows us to drop a lot of complexity.
Instead, complain if somebody calls gdk_x11_window_get_xid() on a
non-native window.
We cannot make random windows native anymore because there's no GSK
renderer associated with them, so we cannot draw them.
gdk_window_create_vulkan_context() now exists and will return a Vulkan
context for the given window. It even initializes the surface. But it
doesn't do anything useful yet.
Adds the gdk_display_ref_vulkan() and gdk_display_unref_vulkan()
functions which setup/tear down VUlkan support for the display.
Nothing is using those functions yet.
This is a way to query the damaged area of the backbuffer.
The GL renderer uses this to compute the extents of that damage region
(computed via buffer age) and use them to minimize the area to redraw.
This changes the semantics of GL rendering to "When calling
gdk_window_begin_frame() with a GL context, the area by
gdk_gl_context_get_damage() needs to be redrawn and every other pixel of
the backbuffer is guaranteed to be correct.
After gdk_window_end_frame() on a GL-drawn window, the whole backbuffer
must be correct.
We can always glXBufferSwap() now because of this.
... instead of a gl context.
This requires some refactoring in the way we mark the shared context as
drawing: We now call begin_frame/end_frame() on it and ignore the call
on the main context.
Unfortunately we need to do this check in all vfuncs, which sucks. But I
haven't found a better way.
This way, we can query the GL context's state via
gdk_gl_context_is_drawing().
Use this function to make GL contexts as attached and grant them access
to the front/backbuffer for rendering.
All of this is still unused because GL drawing is still disabled.
No visible changes as GL rendering is disabled at the moment.
What was done:
1. Move window->invalidate_for_new_frame to glcontext->begin_frame
This moves the code to where it is used (the GLContext) and prepares it
for being called where it is used when actually beginning to draw the
frame.
2. Get rid of buffer-age usage
We want to let the application render directly to the backbuffer.
Because of that, we cannot make any assumptions about the contents the
application renders outside the clip area.
In particular GskGLRenderer renders random stuff there but not actual
contents.
3. Pass the actual GL context
Previously, we passed the shared context to end_frame, now we pass the
actual GL context that the application uses for rendering. This is so
that the vfuncs could prepare the actual contexts for rendering (they
don't currently).
4. Simplify the code
The previous code set up the final drawing method in begin_frame.
Instead, we now just ensure the clip area is something we can render
and decide on the actual method in end_frame.
This is both more robust (we can change the clip area in between if we
want to) and less code.
This way we can recommend that applications use the
fullscreen_on_monitor() API on both X and Wayland otherwise they'd
have to keep a path for each backend to achieve this functionality.
