[Lazarus] Video: Fixing anchor docking previews on OSX

Problem: On Macintosh the anchor docking system doesn't provide a preview
window, making arranging docked layouts on OSX cumbersome to say the least.
I think this issue is going to become more important as work progresses on
anchor docking and the sparta docked form designer.

Video detailing my solution:

I put this solution video form because I think a good chunk of code can be
removed from the LCL. Using a tiny bit piece of universal code rather than
many larger different implementations for each widgetset seem desirable to
me. But, the Controls and Forms units need a minor alteration, which might
possibly be something some or the key Lazarus developers resist. Maybe the
my stub procedure could be better placed/organized. You decide.

The issue with patch has been filed here:
