invert UV.x of three.js geometry (if for example watching a textured sphere from the inside)

gistfile1.js

// invert U coordinate
for( var li in geometry.faceVertexUvs )
  for( var fi in geometry.faceVertexUvs[li] )
    for( var vi in geometry.faceVertexUvs[li][fi] )
      geometry.faceVertexUvs[li][fi][vi].x = 1.0 - geometry.faceVertexUvs[li][fi][vi].x;
