Subject: SL-10181, SL-10546

Fix distortion map rendering in deferred mode not including underwater fog effects.

Fix distortion map rendering not including post-deferred content at all.

Fix distortion map rendering not including anything but sky when camera is underwater.

Update sun_up_factor/sunmoon_glow_factor uniforms even when sun disc isn't in use.
