wxLayoutConstraints (which anchors are built upon) are deprecated, but I
don't think they will ever go away entirely.

Anchors are a (currently python-only) simplification of the very complex
layout constraints.  Riaan did a good job of abstracting out of the
contraints a common (but not complete) usage model that could be expressed
in a simple way.  The wxSizers were created with similar purposes (to
provide a layout model simpler than the constraints that handled most cases)
but from scratch instead of building on the layout constraints.
