Additionally:

• Snap Perpendicular now also works for faces.
• Snap Perpendicular can now find multiple points. For example two points on a circular edge.
• For clarity the snapToFace function was renamed to snapToCenterFace.
• To snap to a vertex (f.e. a Draft Point) Snap Endpoint must now be used. This makes more sense IMO and is also consistent with snapping to points in a point cloud.

I wonder if snapping a face, near the edge, with near snap activated, shouldn't snap to the nearest edge instead... But that's just a thought for later..

[Roy-043]

It is possible to snap to the edge of a face by just making sure it is highlighted. In rare cases the user may need to change the DrawStyle, although using Wireframe can be confusing in a crowded scene.

The code related to oldActive must be removed.
