Scaling method for an optional image scaling pass. This can be used to create a pixelated effect while still preserving the ability to have filtered display scaling.
In addition, it can be used to set the scaling filter for a postprocess pass, to be implemented in the future.
The following methods are available:

Nearest

Uses nearest-neighbor scaling.

Bilinear

Uses bilinear scaling. 8-bit display modes will always use nearest scaling for this pass.
