Implements

ITextMarkupSetQuadPoint(Int32, QuadPoint)
Remarks
To make this QuadPoint compatible with Adobe Acrobat|Reader, you can use either clockwise or counterclockwise order, but the points p3 and p4 must be swapped. This is because those readers do not follow the PDF specification for TextMarkup QuadPoints.
Remarks
An Array of n QuadPoints specifying the coordinates of nquadrilaterals in default user space. Each quadrilateral shall encompasses a word or group of contiguous words in the text underlying the annotation. The coordinates for each quadrilateral shall be given in the order p1, p2, p3, p4 specifying the quadrilateral’s four vertices in counterclockwise order. The text shall be oriented with respect to the edge connecting points (p1) and (p2). The annotation dictionary’s Appearance(AP) entry, if present, shall take precedence over QuadPoints.
