This assistant is meant to help create an ellipse
within a quadrilateral (tetragon).
It helps the user to draw circles in perspective.
The assistant draws the vanishing points that fit
that perspective.

This commit however doesn't have correct calculations,
so the end result assistant doesn't work properly.
