-/**
-Polymer.IronFitBehavior fits an element in another element using `max-height` and `max-width`, and
-optionally centers it in the window or another element.
-
-The element will only be sized and/or positioned if it has not already been sized and/or positioned
-by CSS.
-
-CSS properties               | Action
------------------------------|-------------------------------------------
-`position` set               | Element is not centered horizontally or vertically
-`top` or `bottom` set        | Element is not vertically centered
-`left` or `right` set        | Element is not horizontally centered
-`max-height` or `height` set | Element respects `max-height` or `height`
-`max-width` or `width` set   | Element respects `max-width` or `width`
