  Scale and translate are the keywords.
  You can make it for example this way: Translate the heightfield so that
its corner is at the origin and scale it so that it's sized 1x1 (if I
remember right, this is the default without translations or scales).
Then apply the texture and translate and scale it (the texture) so that
its corner is also at the origin and its dimensions are equal to the
heightfield dimensions. (If I still remember right, you have also to rotate
the texture 90 degrees but I suppose you have already guessed that)
