Several of the world files included with this release will not be useable
without some additional textures.  I was hesitant to include these textures
because the legality of distributing them is questionable.  I've made
bastardized version of a few (huge2.tcl and huge2.world) which will work
with the included texture library.  The originals were created by
Thomas Malik using the world editor which he wrote.
