Brew MP 1.0.2
This interface is implemented by each extension that is used to extend
Trigml by adding support for new elements, and by Trigplayer itself to
provide support for the built-in Trigml elements.
A Trigml extension object is created when the player calls
ISHELL_CreateInstance() with the class id of the required extension.
If successful, a pointer to the Trigml extension will be returned in
the 'ppobj' parameter of ISHELL_CreateInstance.
The Trigml extension object is reference counted. When you are done
with your reference to the Trigml extension object, you should release
it. Any specific cleanup will be handled for you when all references
