This enables HiDPI support for GTK+ on Windows, so that the
fonts and window look better on HiDPI displays. Notes for the current
work:
-The DPI awareness enabling can be disabled if and only if an application
manifest is not embedded in the app to enable DPI awareness AND a user
compatibility setting is not set to limit DPI awareness for the app, via
the envvar GDK_WIN32_DISABLE_HIDPI. The app manifest/user setting for
DPI awareness will always win against the envvar, and so the HiDPI items
will be always setup in such scenarios, unless DPI awareness is disabled.
-Both automatic detection for the scaling factor and setting the scale
factor using the GDK_SCALE envvar are supported, where the envvar takes
precedence, which will therefore disable automatic scaling when
resolution changes.
-I am unable to test the wintab items because I don't have such devices
around.

GtkLevelBar supports adding custom offsets as style classes, and they
are applied whenever the :value property matches. The current code,
however, only updates any CSS nodes when an offset is found, causing
it to not update when a discrete value changes but no custom offset
is added.
Fix that by always updating the CSS nodes.

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.

gdk_wayland_window_attach_image() is normally called from
gdk_window_end_paint() to notify the compositor of newly staged drawing.
If any of the drawing code inadvertently dispatches the wayland event
loop (for instance with a gdk_flush() call), then it's possible that by
the time gdk_window_end_paint() is called, the staged drawing is already
destroyed.
This commit bypasses the attach_image call in scenarios where the staged
drawing is prematurely dropped.

Update the GDKGL implementation:
-Allow legacy contexts to be created.
-Use finer-grained attributes to ask for a pixel format when possible,
which also adds support for anti-aliasing
In fact the changes here are required for GTKGL to work properly on
Windows for 4.x.
Note that creation of gles contexts are not done here, as the system does
not support such contexts directly on Windows, but only through means such
as ANGLE, which is a totally different issue here.

For some reason we end up allocating the colorplane widget
before it is realized, and then never initialize the surface.
Fix this by explicitly doing it on realize.

GDK defaults to asking for an OpenGL 3.2 Core Profile, but if we get a
legacy profile from the underlying windowing system, the OpenGL version
will be fixed to 3.0. If that happens, we need to set the legacy bit on
the GdkGLContext, since that bit will be used to determine the version
and type of GLSL shaders that will be used by application and toolkit
code alike.

Now that the use_es field is an int with a possible negative value, we
cannot use it its truth value directly; we need to check if it's a
positive value, instead.

With best-effort, try to use gdk_window_move_to_rect() more often, when
all pieces fit together. For the non-legacy paths to be triggered for
when gtk_menu_popup_for_device() or gtk_menu_popup() were used, the
following conditions must be met:
1) There is no custom positioning function specified
2) The menu is attached to a widget (using gtk_menu_attach_to_widget())
3) There is a associated grab device

We've already set ->use_es correctly at context creation time, all this
can possibly do is change our mind about what kind of GL we're using.
