Great add-on. Can you update it to center svg files?

This review is for a previous version of the add-on ( 

Okay, there are three problems with doing this that I can see:

a) SVG is complicated (SVG images are closer to webpages than to images), and I'm not at all sure I can get centering that works for all SVG images without breaking anything.
b) I don't want to add every feature that anybody asks for; every feature I have to maintain but don't use myself is another reason to put off doing updates.
c) SVG documents are a different type of document to Image documents, and ODIS can't handle multiple document types yet.

I'll have to deal with (c) anyway, whenever I decide to make ODIS work on video documents, so I'll try and do this then... but I probably won't be doing that soon, since I have other extensions I need to work on.
