+formatting data used when drawing to the graphics device.

+Implementors of derived classes need to ensure that, in addition
+to anything else it does, their overload of GetExtendedInterface
+reacts to being prompted with the UID KInlineTextApiExtensionUid
+by returning their class cast as an MTmInlineTextSource. It should
+also invoke GetExtendedInterface on its other parent for any
