--[[
You would like to anchor "control" to "anchorTo".
anchorTo will not move.
This function determines the best fit for control so that anchorTo
is not obscured and so that control fits in the window.
NOTE: anchorTo can't be nil...it MUST be a valid control.
The most common use of this function is to anchor a really big window, like a tooltip,
to a really small window, like an actionbutton or inventory slot.
