// This file contains all the public VTables used. Note that even
// though this is a public header, the code here is UNSTABLE. That is,
// the structures may change without notice (though not between bug
// fix releases).
//
// For that reason use this with care and only for code where it is
// unpractical for you to use interfaces directly.
