GDK-Win32/4.0: Improve GL on Windows

Desktop / GNOME / GTK - Chun-wei Fan [src.gnome.org] - 28 October 2016 02:56 UTC

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.
