Add OpenGL Support for the GDK Windows Backend This adds support for OpenGL to the GDK Windows backend using the WGL API calls, which enables programs that uses the GTK+ GLArea widgets to work on Windows as well. This also adds a simple utility function to query for the version of OpenGL that is supported by the Windows system, like the one provided by the X11 backend. Many thanks to Alex (and Emmanuele, who started the OpenGL integration in GTK+) who offered advice and help along the way, as well as the X11 and Wayland backend for this work to refer to and to model upon. https://bugzilla.gnome.org/show_bug.cgi?id=740795

GDK-Win32: Split GL context creation in two phases Like what is being done in the X11 and Wayland backends, create the GdkWin32GLContext in 2 steps, where we only create the actual WGL context in _gdk_win32_gl_context_realize(). https://bugzilla.gnome.org/show_bug.cgi?id=741946

GdkWindow -> GdkSurface initial type rename This renames the GdkWindow class and related classes (impl, backend subclasses) to surface. Additionally it renames related types: GdkWindowAttr, GdkWindowPaint, GdkWindowWindowClass, GdkWindowType, GdkWindowTypeHint, GdkWindowHints, GdkWindowState, GdkWindowEdge This is an automatic conversion using the below commands: git sed -f g GdkWindowWindowClass GdkSurfaceSurfaceClass git sed -f g GdkWindow GdkSurface git sed -f g "gdk_window\([ _\(\),;]\|$\)" "gdk_surface\1" # Avoid hitting gdk_windowing git sed -f g "GDK_WINDOW\([ _\(]\|$\)" "GDK_SURFACE\1" # Avoid hitting GDK_WINDOWING git sed "GDK_\([A-Z]*\)IS_WINDOW\([_ (]\|$\)" "GDK_\1IS_SURFACE\2" git sed GDK_TYPE_WINDOW GDK_TYPE_SURFACE git sed -f g GdkPointerWindowInfo GdkPointerSurfaceInfo git sed -f g "BROADWAY_WINDOW" "BROADWAY_SURFACE" git sed -f g "broadway_window" "broadway_surface" git sed -f g "BroadwayWindow" "BroadwaySurface" git sed -f g "WAYLAND_WINDOW" "WAYLAND_SURFACE" git sed -f g "wayland_window" "wayland_surface" git sed -f g "WaylandWindow" "WaylandSurface" git sed -f g "X11_WINDOW" "X11_SURFACE" git sed -f g "x11_window" "x11_surface" git sed -f g "X11Window" "X11Surface" git sed -f g "WIN32_WINDOW" "WIN32_SURFACE" git sed -f g "win32_window" "win32_surface" git sed -f g "Win32Window" "Win32Surface" git sed -f g "QUARTZ_WINDOW" "QUARTZ_SURFACE" git sed -f g "quartz_window" "quartz_surface" git sed -f g "QuartzWindow" "QuartzSurface" git checkout NEWS* po-properties
