Refer to the following table for command descriptions:

Command | Description
    input_rectangles

    defined_output_rectangle
| defined rectangle region to be returned

This function is optional. If supplied, it is called before the rendering of the process at a frame. The function should calculate and return the defined region for all outputs from the defined regions supplied for each input.

The supplied rectangle regions do not take into account the current render scaling, and the returned rectangle region should not either.

If not supplied, the output defined rectangle region defaults to the same as the first input.

The supplied input_rectangles regions do not take into account the current render scaling, and the returned defined_output_rectangle region should not either.
