Unity and GL context problems
How do we detect when Unity recreates the GL context?
1. By using XXXGetCurrentContext (eg: glXGetCurrentContext). Problem: sometimes the context is different but the pointer returned by XXXGetCurrentContext is the same.
2. By using glIsBuffer(name) against a VAO. This is not 100% safe because 'name' could be a valid handle in the current context, one created by Unity for example.
3. Using the native callback API (UnityGfxDeviceEventType). Problem: not implemented.
