Currently, there is support for:

• Circle
• Point (a typedef of 2D Vector)
• Line
• Rectangle
• Oriented Rectangle

A line consists of a start and end variable, each are Point2D instances. For convienence, the following functions are present:

• Length()
• LengthFast(), which returns the distance without performing the final, expensive sqrtf function.

A 2D circle consists of a radius and a origin (Point2D). It has no other special features in it's own class.

A 2D rectangle consists of an origin, (Point2D) and a size (Vector2).

A helper constructor is also given, named InitializeWithMinAndMax which takes 2 Point2D variables and will initialize the Rectangle for you.

Additionally, this class also has the following helper functions:

• GetMin()
• GetMax()
