*-------------------*
*   Description:
*       This is the primary method that SAPI calls to render text.
*-----------------------------------------------------------------------------
*   Input Parameters
*
*   pUser
*       Pointer to the current user profile object. This object contains
*       information like what languages are being used and this object
*       also gives access to resources like the SAPI master lexicon object.
*
*   dwSpeakFlags
*       This is a set of flags used to control the behavior of the
*       SAPI voice object and the associated engine.
*
*   VoiceFmtIndex
*       Zero based index specifying the output format that should
*       be used during rendering.
*
*   pTextFragList
*       A linked list of text fragments to be rendered. There is
*       one fragement per XML state change. If the input text does
*       not contain any XML markup, there will only be a single fragment.
*
*   pOutputSite
*       The interface back to SAPI where all output audio samples and events are written.
*
*   Return Values
*       S_OK - This should be returned after successful rendering or if
*              rendering was interrupted because *pfContinue changed to FALSE.
