Annotation
See example for LPFNIG_ART_TEXTOVERFLOWNOTIFYFUNC callback function.
It can be applied for ART_MARK_TYPED_TEXT, ART_MARK_ATTACH_A_NOTE and ART_MARK_TEXT_FROM_FILE marks only. If the mark has overflowed text the lpdwOverflowedTextLength returns the number of overflowed text characters. Otherwise it returns 0.
The lprcPreferableBounds returns rectangle of mark bounds enough to draw the whole text. It is made by expanding the mark bounds in direction the drawn text (from top to bottom direction) is cut to the image window clip bounds.
