Fix Scroll effect coordinates
The coordinate computed for the text's top edge was actually used for
the baseline of the text's top line, causing the first line's ascender
to protrude up and the whole text to be shifted up by that ascender.
(Note: in this context, bbox.y_min == text_info->lines[0].asc.)
