The layer the refraction split moves the UNPARTITIONED meshes onto for one render
call: meshes drawn by three's own materials (physical glass without refract_data,
physical opaque surfaces), which cannot classify their fragments against the glass
depth and are therefore drawn whole in pass A and left out of pass C. Restored in the
same finally. Never persistent.
