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: Add cursor theme support to W32 backend Load themed cursors from the same places they are loaded on freedesktop systems, but use W32 API functions to do so (works for .cur/.ani cursors instead of X cursors). Refactor the code for cursor handling. Prefer loading cursors by name. Do not load actual cursors when loading the theme. Find the files and remember the arguments/calls for loading them instead. Keeping HCURSOR instance in the hashmap would result in multiple GdkCursors using the same HCURSOR. Given that we use DestroyCursor() to off them, this would cause problems (at the very least - DestroyCursor() would fail). Store GdkCursor instances in a cache. Update cached cursors when theme changes. Recognize "system" theme as a special (and default) case. When it is set, prefer system cursors and fall back to Adwaita cursors and (as a last resort) built-in X cursors. Otherwise prefer theme cursors and fall back to system and X cursors. Force GTK to use "left_ptr" cursor when no cursor is set. Using NULL makes it use the system default "arrow", which is not the intended behaviour when a non-system theme is selected. Ignore cursor size setting and query the OS for the required cursor size, as Windows (almost) does not allow setting cursors of arbitrary size. https://bugzilla.gnome.org/show_bug.cgi?id=749287

win32: handle WM_DISPLAYCHANGE globally Instead of handling WM_DISPLAYCHANGE on every GdkWindow, only handle it on an ad-hoc hidden window we create when opening the display. This has two reasons: 1) we want emit the display::size-changed signal even if there are no gtk windows currently open 2) we want to emit the signal just once and not once for every window https://bugzilla.gnome.org/show_bug.cgi?id=757324

GDK-Win32/4.0: Improve GL on Windows 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 is 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. https://bugzilla.gnome.org/show_bug.cgi?id=773528
