// This script allows you to display a popup that does not pop
// off the edge of the screen if the link is toward the edge
// If the link sits on the edge of the screen, the popup will
// pop the other direction
// also allows a popcenter in the middle of the screen --%>

// height and width, if 0 or negative, are understood as the boundary that is
// substracted from the full visible screen, i.e. 0 means full screen, and -20
// means an almost full screen, except a narrow stripe of 20 pixels around the popup.
// position=1 POPUP: makes screen display up and/or left,
//    down and/or right
// depending on where cursor falls and size of window to open
// position=2 CENTER: makes screen fall in center
// asWindow, if true, shows the popup with scrollbars, and resizable, in order
// to show the contents
