//*************************************************************************************
// Swatch cache delegate
//*************************************************************************************
/*!
The swatch cache delegate is used to temporary store intermediate rendering results
in cache when an fx is being edited.
Input fxs of an edited fx are typically requested to produce the same results multiple times
as parameters of their schematic parent change - so, caching these results is a remunerative
practice as long as the fx is open for edit.
This delegate stores resources on two different levels: one is directly related to swatch rendering,
while the other is used to cache results on the other rendering contexts.
In the swatch case, we store the above mentioned input results associated with the current scene
scale, releasing them when the scene scale changes; plus, the resource associated with the current
output is also stored.
In other rendering contexts, the scene scale can be assumed constant - so the above distinction
is unnecessary. All results from the input fxs are stored until the edited fx is unset from the swatch.
Please observe that variations in the scene context - such as frame change, schematic changes, scene changes
and so on - actually cause the fx to be re-set for edit in the swatch. Once this happens, the previously
stored results are conveniently flushed from the cache.
*/
/*NOTE: This can be extended in case we realize multiple swatch viewers... It should be sufficient to map
a swatch pointer to its associated cache data - the advantage being that cache resources are shared at the
same scene zoom.*/
