There will be no rounding errors. As you can see in my notes after the
script, there is no recalculation to return to the prior size. I save
the original value and just reassign it.

Meanwhile, I have reworked the script per your suggestion, and posted on
the wiki:

http://wiki.scribus.net/canvas/Fitting_an_Image_to_its_Frame#fitimage2frame_v2.py

It may be that your mods didn't work because scaleImage() is deprecated,
the new command is setScaleImage().
