You could easily make some very brief python scripts that "fix" the
scaling. setImageScale() also uses percent, but you should be able to
figure out the percent you need to get a certain ppi depending on the
source.
Perhaps some input from the PIL (Python Imaging Library) might even
detect the resolution of the source and automagically do the calculation
for you.
