Initial testing setup for clouds.
Unwrapped test model so that UVs are available for sampling heightmap.
Added functionality for storing shared vertices to avoid finding them every time a cloud is created. Shared Vertices can be computed upon game start to avoid any finding during play.
Added more skyfilters so that they drop visibility to zero smoothly. Generating clouds (textured as molten comets) on right click.
Generating clouds randomly around the player
