Description

Draws the outline of or a solid ellipse

ABI suggestion

r1 = colour
r2 = x size
r3 = y size
r4 = x position
r5 = y position

no result

Algorithm suggestion: Bresenham's line algorithm.
It allows drawing pixel-by-pixel of a straight line.
It's extension, the Midpoint circle algorithm can be used to draw circles and ellipses.
