I guess what I'm wondering is if I had a version of the texture (T1) with sslt
enabled, and another version without (T2), and then used

texture {
   gradient x
   texture_map {
      [0.0 T1]
      [0.75 T1]
      [0.75 T2]
      [1.00 T2]
   }
}

Would I get the slowdown from SSLT over the whole object, or just the portion of
the last 25% of the object in the X direction?
