Fits an ellipse to a set of points.
Remarks:
During a filtering pass, the points that are too distant from the model are discarded. During a model fitting operation, the "filtering" process can be invoked to remove outliers, i.e. points that were located significantly far away from the fitted model (so that their position is dubious).
This method returns a "direct" eVision.EEllipse, see eVision.EEllipse.IsDirect.

Computes the distance between a point and an ellipse.
Note that we compute the distance between the point and its projection on the ellipse. This is not always the shortest distance.
Remarks:
When the ellipse is restricted to an arc and the orthogonal projection of the point onto the ellipse falls outside this arc, the distance to the closest endpoint of the arc is returned instead.
