Celestia v1.3.0pre6: Nebula brigntness-- off or on

[selden]

Nebula "illumination" is either off or on.

When the limiting magnitude is 1.80 or less, no Nebulas are visible.
When the limiting magnitude is 2.00 or more, Nebulas are at their maximum brightness.

It'd be nice if their brigntness varied.

So far for the nebula wishlist, I have:

- Brightness control
- Easier orientation control
- Multiresolution textures (general request for 3DS meshes)
- Separate control for showing galaxies and nebulae

And of course:

- Volumetric rendering of nebula

That looks like a good list!

Personally, I'd like to be able to specify a texture without having to edit the 3DS file, but I think that assumes a single texture for the whole object (like those used for planet surfaces). That's not so good for the general case where multiple textures may be needed for a complicated object.
