public Vector2[] getAxes(Vector2[] foci, Transform transform)
ConvexShape.
Given some points, this method will return the separating axes for
this Shape's voronoi regions also. The voronoi axes will not be included
if the foci array is null.
The points in the foci array are assumed to be in world space.
The returned axes are normalized.
