- Fix for mantis #1975. Added, to .trn files:
[Texture]
InvisibleTexture = "" // texturename w/o extension, e.g. "mire" instead of "mire.tga"
If this entry is specified, any terrain chunk w/ that texture set
on it will not be drawn at all. Skipping a rendering call to DX9 is
*FAR* more efficient that "drawing" an all-alpha'd out texture, and
should help avoid some exploits. Tested w/ this set to "mire" on
bridges2i.bzn; remember to omit any and all texture extension.
