sticker problem

[RobinHankin]

File stokes_theorem.png is needed by stokes_stickermaker.R but is not on the repo, nor are instructions for how to make it.

After pdflatex stokes_theorem, which produces stokes_theorem.pdf, use:

pdftoppm -r 1500 -x 5600 -y 2990 -W 1500  -H 580  -singlefile -png stokes_theorem.pdf "stokes_image"

Many aspects of the sticker-making process are broken. Commit 7121600 now creates stokes_theorem.png with a purple background, obviating the need for gimp (note in passing that the canonical gimp method of changing background, viz fuzzy select tool, followed by bucket fill, does not work very well and creates small pixelised white regions at the border).
But stokes_stickermaker.R creates stokes.png that has dimensional mismatches.
