Enable per-instance parameters on a custom-shader layer. Existing and newly added sprites
start at zero. Idempotent; ordinary layers retain their layout until explicitly enabled.
The engine transports these values without interpreting them or changing color, UV or depth.
Enable depth-hosted layers before addDepthHostedSpriteLayer. Late enablement is supported
only by the pure-2D SpriteRenderer, which refreshes its pipeline each frame.
