A set of geometric primitives for dart.

Affinity uses the MIT license as described in the LICENSE file, and semantic versioning.

Everyone loves to write these classes. Vector, Rectangle, etc... are familiar to most every programmer and they are easy to reason about. It is therefore tempting to simply roll your own for your own needs. However, this makes it more difficult to interoperate with other libraries who have also rolled their own such classes. Thus, i've written Affinity with the following goals:

• 100% unit test coverage.
• Micro benchmarks ensure performance improves rather than degrades over time.
• Only constructors (including factory constructors) may allocate memory.
• Focus on useful constructs, in particular those for 2D graphics.

I plan to take a conservative approach to the amount of classes and functions in this library; i.e. it shall not be a dumping ground for any sort of geometric code. Rather, it will remain true to the above goals and focus on the most commonly used structures.
