It fairly easy to make things thread safe and support multiple devices per thread, very roughly
you have to:
Add the OpenGL context to the device structure.
Make a per-device critical section.
Whenever a call is made enter the critical section
Then check that the current active context is the same as the context on the device.
If not then make the device context active.
I wanted to finish state management before making things threadsafe and support multiple devices
