Remarks:
- The value of the text string is the path to a file. The annotation is drawn using the contents of this file.
- If lpszTextBuffer is NULL, then the number of bytes required to copy the annotation text string is written to pnDataSize.
- If lpszTextBuffer is not NULL, then the actual number of bytes copied to lpszTextBuffer is written to pnDataSize.
