I think there are basically 2 kinds of drop shadows that are desired

- drop shadow related to an object like a frame or shape.

- drop shadow related to something inside a frame, such as text or 
perhaps a Bezier curve or other vector graphic.

Some support could come from Scribus supporting Gaussian blur such as 
can be done in Inkscape and exported in an SVG. A start might be to be 
able to import an SVG with Gaussian blur, then later perhaps be able to 
create blur inside Scribus.
