[2.1.8] fluid.draw_as_glow not working

[KiwiHawk]

It seems fluid.draw_as_glow does nothing.

After some experimentation, I found that it only works if expansion shaders feature flag is enabled.

Is it possible to have this available without any feature flags? If not, then at minimum can the docs be updated please?

From what I can tell the behaviour will not change, so I've added a note about the feature flag to the docs for the next release.
