Graphics primitive. Represents a box on a 2D field. Note on area calculation: The smallest box that can be represented is 1 * 1, as it counts the endpoints as part of the box. This behavior got added with 0.10.0, to standardize various behaviors of the engine, and fix some odd behavior the GUI drawing functions had.
Graphics primitive. Represents a single point on a 2D field.
Defines polygons for sprite transformation (eg. scaling, rotation). Most likely will be removed due to lack of use.
