#### Notes

* `std::min` and `std::max`
  * `min` and `max` are defined as macros on some systems. `std::min` and `std::max` may not be used. Use `cmMinimum` and `cmMaximum` instead.
* `size_t`
  * Various implementations have differing implementation of `size_t`. When assigning the result of `.size()` on a container for example, the result should not be assigned to an `unsigned int` or similar. `std::size_t` must not be used.
