Subject: * Terrain filters! - Think photoshop-style filters for terrain. *
Terrain filters may be written in either C# or JavaScript and loaded at
runtime Use: terrain csfilter somefile.cs -- Loads a C# filter terrain
jsfilter somefile.js -- Loads a JavaScript filter Once a terrain filter has
been loaded, you can use the command as normal, eg terrain demofilter
