/**
* @class vtkTransformTextureCoords
* @brief transform (scale, rotate, translate) texture coordinates
*
* 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 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.
