data NaiveDraw

FOR TESTS ONLY. For production, please use Imj.Graphics.Render.Delta.

Naive rendering for the terminal : at every call it sends color and position change commands, hence screen tearing happens very quickly as a consequence of stdout buffer being automatically flushed to avoid overflow.

To fix this problem, Imj.Graphics.Render.Delta uses double buffering techniques to limit the actual number of rendering commands sent to stdout.

Draw NaiveDraw

Direct draw to stdout : don't use for production, this is for tests only and creates heavy screen tearing.
