Step 1 is to figure out why wglCreateContextAttribsARB fails exactly. This
situation might be avoidable for the NVIDIA drivers. Failing that, a bug with
NVIDIA with might be prudent to get this fixed at the source.
As for a workaround, the only real way to know when the GL context has been
created is by overriding the 'create-context' signal on GstGLDisplay and
creating the GL context there with the cinder GL context not current.
