At this point, I don’t know what negative values mean in a texture coordinate point value and what I should accept for an IFS. It seems like -99999 is dreadfully wrong, but per the spec above, any float value is acceptable. I will check the IFS spec, but if no one has a use case, I recommend reducing the range of the texture coordinate point values.</pre></div>
