* The library is specialized on the primitive types rather than attempting to
support all types in a single class hierarchy. `pythagoras.f` and
`pythagoras.d` provide essentially the same functionality using 32-bit and
64-bit floating point values throughout. `pythagoras.i` is specialized on int
and contains none of the curved geometry classes. It is targeted toward
applications that need "pixel geometry".
