<DD>Function to call to get the extension of a specified context.
If the Exentsion object for that context has not yet been created then
and the 'createIfNotInitalized' flag been set to false then returns NULL.
If 'createIfNotInitalized' is true then the Extensions object is
automatically created. However, in this case the extension object
only be created with the graphics context associated with ContextID..

<DD>setExtensions allows users to override the extensions across graphics contexts.
typically used when you have different extensions supported across graphics pipes
but need to ensure that they all use the same low common denominator extensions.
