* TODO features to add
++ read this as example, and apply improvements/fixes where applicable:
+ http://blog.rogach.org/2015/08/how-to-create-your-own-simple-3d-render.html
+
+ Partial region/frame repaint: when only one small object changed on
the scene, it would be faster to re-render that specific area.
+ Antialiazing. Would improve text readability. If antialiazing is too
expensive for every frame, it could be used only for last frame
before animations become still and waiting for user input starts.
+** Render only visible polygons
++ This would significantly reduce RAM <-> CPU traffic.

- + General algorithm description:
- + For each horizontal scanline:
- + sort polygon edges from left to right
- + while iterating and drawing pixels over screen X axis (left to
- right) track next appearing/disappearing polygons.
- + For each polygon edge update Z sorted active polygons list.
- + Only draw pixel from the top-most polygon.
- + Only if polygon area is transparent/half-transparent add
- colors from the polygons below.

- + As a bonus, this would allow to track which polygons are really
- visible in the final scene for each frame.
