title: problems about texture coordinate in Obj format
body: <p>as far as i know, texture coordinates should range [0,1]
  but in this obj file as follow, the texture coordinates seem to range [0,2]</p>

  <p>Why the texture ordinates here can be greater than 1 ? Can anybody explain it to me? Thanks!</p>
  
  <p>you see the texture seems weird
