This patch changes the 'age' counting previous approach taken verbatim from clutter and changes it for a counter of validated caches and an index to the last cached value which we use to round-robin through the cache if ever a widget is requested for more than 3 contextual sizes (cache is reduced by 3 * sizeof (int) per widget private data).
