this is a request for help.
at least, it will have it on X11 and Wayland.
if you are using (or you plan to use) GTK+ 3.x on Windows or MacOS X, and
you know how to use OpenGL on those two platforms, please consider helping
out the GTK+ developers by implementing the
using WGL and AppleGL.
we’d really like to get all backends working out of the box when we release GTK+ 3.16.0, next year.
testing and feedback is also very much appreciated.
Update: thanks to Brion Vibber, there’s already a preliminary patch
GdkGLContext on MacOS X. now it’s up to the Windows
developers to step up their game. :-)
Update: Fan Chun-wei is looking into Windows support, so we should have a patchset for it soon!
