That was one of my main concerns for optimization. If you look at my
code, you'll see that I'm using the ImageMagick library
(image-size (create-image c) t)
The library does not seem to provide any feature for _resizing_ an
image.
I hope you can prove me wrong.
"convert" should also be a `defvar`/`defcustom`, I'll change that.
