The pattern of gen context, share context, free context, then allocate
a shared GL object in the second context would cause a use-after-free
of the ContextImpl as a GLFactory. Fix this by passing the factory
as a parameter to the resource manager allocation methods instead of
storing the factory pointer. This allows the same ResourceManager to
work with separate Context implementations, which will work with
non-virtual contexts.
