overridevirtual

Get input operation area being read by this operation on rendering given output area.

Implementation don't need to ensure r_input_area is within input operation bounds. The caller must clamp it. TODO: See if it's possible to use parameter overloading (input_id for example).

Parameters

input_idx	Input operation index for which we want to calculate the area being read.
output_area	Area being rendered by this operation.
r_input_area	Returned input operation area that needs to be read in order to render given output area.
