1 - orthographics projection - did I forget this lol?
2 - Add option to compute sin with Bhaskaras approx instead of using a LUT.
3 - ADD THIS!!! Rendering could be made faster by reusing the mapped vertex
4 coordinates between iterations when processing triangles: this supposes that
5 a triangle that's being rendered quite likely shares 1 or 2 vertices with the
6 previously rendered triangle, so there is no need to expensively transform and
7 screen-map all its vertices! ALSO: create a function that optimizes the model
8 for rendering, i.e. rearranges the triangle order to favor this optimization!
