Beware - you're moving the texture here, not just scaling it!

Note again that scaling /always/ has its origin at <0,0,0>; if you do 
this /after/ translation, it's no longer the <0,0> of the image, but 
rather its <-0.25,0>. To scale from the /image's/ <0,0>, you need to 
scale first, and only then translate; you'll probably need to fix the 
translation vector though:

     scale <1.5,1,1> translate <1.5,1,1>*<0.25,0,-1>
