<constant name="BG_KEEP" value="5" enum="BGMode">
Keeps on screen every pixel drawn in the background. This is the fastest background mode, but it can only be safely used in fully-interior scenes (no visible sky or sky reflections). If enabled in a scene where the background is visible, "ghost trail" artifacts will be visible when moving the camera.
