Dummytile (DEF)
dummytile <tilenum> <width> <height>
dummytilerange <start tilenum> <end tilenum> <width> <height>
Used in DEF files to create a blank tile at location <tilenum> of the dimensions <width> and <height>. This allows the creation of placeholder tiles for use with texture without having to edit .ART files.
tilefromtexture can be used to add the texture offsets.
