Transform documentation cut off

[callym]

In the documentation, the sentence A trait representing an affine transformation that can be applied to points or vectors. An affine transformation is one which is cut off. I'm not sure how it's meant to end and don't know enough about what an affine transformation is to fix it, but thought I'd point it out 😄

Hello, new guy here considering to use this library.

Even in the latest documentation version 0.18.0 no one has fixed this. It seems like other documented traits don't have that much explanation other than a Wikipedia link. I will try to make a pull request that simply removes that broken sentence.
