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

xdg_shell v6 allows grabless popups, whose behavior is not that
different from override redirect windows with no grab to take
keyboard input (and pointer events outside).
This means we can relax the requirement to have a grab before
creating an xdg_popup. The warning is still useful to have so
people stop relying on gdk_window_show();gdk_device_grab() being
an ok pattern to popup a window, it's been moved to wayland
implementation of gdk_device_grab() instead, so we warn if trying
to grab a GDK_WINDOW_TEMP window that's already visible.

the darker bottom border used on buttons looks bad on circular ones
so now a gradient clipped on the border-box and a transparent
border is used in that partcular case.
See https://bugzilla.gnome.org/show_bug.cgi?id=771205 for details.
$button_fill contains the background-image property value of
buttons, having it readable outside the drawing mixin allows, for
example, stacking background images in an easier way.
Make the Makefile.am targets for generating the Visual Studio projects re-generate the
project files and the header listings whenever the Makefile.am's that include
build/Makefile.msvcproj changes, so that whenever a source/header is added, they will
be reflected in the projects and in the property sheets that are used to copy the
headers.
Also ensure that these are applied to the vs11, vs12 and vs14 projects when this
happens, as they are copied and processed from the Visual Studio 2010 projects.
