Oriented rectangle
An oriented rectangle is very similar to a non-oriented (Axis Aligned) rectangle. They both have a Position and a size, but the oriented rectangle also has a Rotation. Rotating a rectangle will allow us to better approximate the shape of objects as shown in the following diagram:
Getting ready
Unlike the Rectangle2D, we're going to represent an OrientedRectangle using a center point and half-extents. Additionally, we're also going to store a Rotation. It makes no sense for an oriented rectangle to have a min or max, so we're not going to implement these helper functions for the OrientedRectangle structure.
The reason we represent the rectangle this way is because it will make rotating objects relative to the rectangle easier. As an added bonus, by doing this we will have covered all three methods described earlier to represent a rectangle.
