How to scale a texture in a shader without tiling?

Question

I need to write a shader that allows me to change how a texture is displayed in a game object's mesh by adjusting some parameters. I've already thought in change the texture UV values, and move a texture is not a problem, but I could not scale it without a tiling effect, which is not desired. For my needs the texture must not repeat along the mesh when I scale it down. Any suggestions?

To be more clear, look at the image, that shows the same plane with the same texture, but with different parameters values.

Try setting the wrap mode of the Texture to Clamp: http://docs.unity3d.com/Manual/class-TextureImporter.html
