Maybe handling a wxPoint Array,
and inserting the shape of an ellipse into it,
is faster, but still not the best.
wxRegion(size_t n, const wxPoint *points, int fillStyle = wxWINDING_RULE)

Also the question is, how accurate you want the ellipse to be,
the less Points you have, the faster it is probably.
