Also:
* Move stuff around to a builtin/ folder
* Separate out classes to follow my one-class-per-file convention
* Samples are renamed to the underscore convention
I just like the word "sprue", and it's more descriptive than our original choice of "template". If I had to start Squib all over again, I would probably name it "Sprue" :P
* Playing with PDF support
* Added background
* Added rectangle
* Split save to save_pdf and save_images since PDFs are way different
* Working on text rendering (non-pango for now, but that'll change)
