popup does not have a border. As soon as dragging
starts and "pos" is "center" it is changed to
"topleft".
+ dragall TRUE to allow the popup to be dragged from every
+ position. Makes it very difficult to select text in
+ the popup.
resize TRUE to allow the popup to be resized with the mouse
by grabbing at the bottom right corner. Has no effect
if the popup does not have a border.
