// | Tarts stands for Terminal Art. Tart is a terminal renderer that uses a |
// | render buffer like system that takes csprites or character sprites and |
// | displays them in the terminal. The render buffer consists of cells and |
// | each cell consists of
// |    - Color
// |    - Rendered Character
// |    - Reset
// | In toaltol around 19 to 24 bytes. This alows for complete controle     |
// | over each cell.
