GDK/Win32: Re-enable libANGLE GLES to work
Hi,
From the commit message, for enforcing using OpenGL/ES API throughout when libANGLE is used for the EGL implementation, since the EGL_KHR_create_context
extension implemented by libANGLE does not support desktop OpenGL adequately.
Basically, we need to force a OpenGL/ES API by using gdk_gl_context_set_use_es()
just prior to really realizing the EGL context in the Windows EGL code.
With blessings, thank you!
