[scribus] resizing objects script

[Gregory Pittman]

Here is a simple script I wrote to a simple task: resize an object, 
width and height, by a specified amount.
The default is 0.5, but you can do multiples, like 2.37

Seems to work on a variety of objects, including vector images, shapes, 
Bezier curves, arcs. It worked with a spiral, but had a redraw issue...?

Here it is:

****script follows********

#!/usr/bin/env python
# -*- coding: utf-8  -*-
#resizeobject.py
