Description:
Inquire if the
current picture is obscured, either totally or partially by another picture. Obscured means
that a picture intersects the current picture and was created more recently. If the input
value for the picture identifier is negative the current picture is tested against all other
overlying pictures; i.e. those created more recently than the current picture. If the picture
identifier corresponds to a valid picture then the current one is only tested against the
given one.
