Pixel-perfect ellipses

Currently, Krita can't draw pixel-perfect ellipses, this is due to the error introduced by using Bezier curves and straight lines to approximate an ellipse. This project aims to make specialised algorithms that work pixel-perfect for common shapes like ellipses. This project also proposes other improvements for pixel art creation.

Work report

22/06/20: The ellipse algorithm is mainly done but lacks tests and needs improvements.
