Print and Save features.
The Print feature is kinda wudgy - it shrinks the canvas down to fit on
a single page, which can make it pretty durn small. It also makes
hardcoded assumptions about page size because I was having a tough time
extracting that info from QPrinter. And lastly, it does a pretty bad
job scaling down the text. All that aside, I can see it being useful
under a very narrow set of circumstances, so here it is.
The Save feature only exports to SVG format, per QPicture's limitations,
and it doesn't even do that correctly. It boggles the mind, really.
