I downloaded that (I'd read that thread but missed the attachment at the top!) and have had a play with the test project.
After a bit of playing around I've got a version of that test project (attached) that allows me to scale an SVG on the fly (kind of brute forcing it a bit, so there may be a slicker, more efficient way of doing it).
However, the test project only reads from a file. I'd like to include the SVG(s) with the executable. I'll play some more, but ideally I'd be able to include the XML of the SVG directly in my project and create the in-UI image from that - that would even allow me to manipulate things like the colours in the graphic on the fly...
