New RTSS textured fog sample

[Mattan Furst]

Just added a new sample to Ogre's trunk.

The sample shows how to implement a simple sub-render state in the RTSS. The sub-render state in question replaces the normal fog functionality with a fog that instead of a constant color draws its end color from a cubic texture.

I'm glad to see some examples of how RTSS can be used!
It's a nice feature too, something quite simple that can increase the visual appeal of your scene tremendously.

I tried out the demo and made a few screenshots for those interested in what it looks like

That skybox example is great. Thanks

Kudos to Matt for the initial sample, just appreciating that someone took it and showed a practical use for the cool feature.

That's a rather nice effect, and a good sample of using RTSS. Kudos
