It's slightly hackish, but would it be possible to do an "isinstance"
check in savefig, and if the first arg is a PdfFile, set "format" to
"pdf" automatically, and if "format" is set to something else raise an
exception? A little hackish because it doesn't necessarily scale to
other formats easily, but it would prevent the user from shooting
herself in the foot.
