 Constructor.

 Destructor.

Add context ctx to the list of references.

Remove context ctx from the list of references.

Remember dl range for deletion in next MakeCurrent or dtor execution.

Delete GL resources registered for destruction.

Find identitfy of current context. Static.

Get identity of a default Gl context. Static.

Get the first GL context with the default identity.
Can return zero, but that's OK, too. Static.

Get the free-type font-manager associated with this context-identity.

Private function called when reference count is reduced.
