A PopupTarget is an unconstrained shape defined by an outline. 
When touched by the mouse cursor, the shape pops up.  
The body includes an argument list and an initialization function. The
argument list specifies the the X, Y of the translation vector, the
expansion ratio, and the raster image for the popup.
The initialization function defines /ItemPath, the stencil of the
target, as a NeWS function that creates a path. It can also
define /HoleColor, the color of the hole left when the target pops up.
HoleColor, which is a NeWS color object, defalts to 25% gray.

Today all the information is in a PostScript form but we will
later develop additional classes easier to author, and authoring tools 
to create objects interactively.
