 `scipy`:
 {{{

 Yes, `PIL` is an optional dependency for both `scipy` and `matplotlib`,
 but I think it's highly recommended to have the modules around for having
 a complete feature set.

 Maybe adding `PIL`/`Pillow` as a hard dependency is wrong, but it may
 certainly warrant a variant (to my mind even turned on by default.)

 `SRPAstro` does formally depend on `PIL`, but only due to
 `scipy`/`matplotlib`. I haven't checked exactly, but I figure it uses
 classes from `scipy`/`matplotlib` which are only available with `PIL`. The
 author confirmed this.
