config/name="3D SubViewport Scaling"
config/description="This demo shows how to scale the 3D viewport rendering without affecting 2D
elements such as the HUD. It also demonstrates how to toggle filtering on a
viewport. This technique can be useful in 2D games as well. For instance, it can
be used to have a \"pixel art\" viewport for the main game area and a
non-pixel-art viewport for HUD elements."
