// .NAME vtkTransformTextureCoords - transform (scale, rotate, translate) texture coordinates
// .SECTION Description
// vtkTransformTextureCoords is a filter that operates on texture
// coordinates. It ingests any type of dataset, and outputs a dataset of the
// same type. The filter lets you scale, translate, and rotate texture
// coordinates. For example, by using the the Scale ivar, you can shift
// texture coordinates that range from (0->1) to range from (0->10) (useful
// for repeated patterns).
//
// The filter operates on texture coordinates of dimension 1->3. The texture
// coordinates are referred to as r-s-t. If the texture map is two dimensional,
// the t-coordinate (and operations on the t-coordinate) are ignored.
// .SECTION See Also
