* This tool flips the specified drawable if no selection exists. If a

*
* This tool performs a possibly non-affine transformation on the
* specified drawable by allowing the corners of the original bounding
* box to be arbitrarily remapped to any values. The specified drawable
* is remapped if no selection exists. However, if a selection exists,
* the portion of the drawable which lies under the selection is cut
* from the drawable and made into a floating selection which is then
* remapped as specified. The interpolation parameter can be set to
* TRUE to indicate that either linear or cubic interpolation should be
* used to smooth the resulting remapped drawable. The return value is
* the ID of the remapped drawable. If there was no selection, this
* will be equal to the drawable ID supplied as input. Otherwise, this
* will be the newly created and remapped drawable. The 4 coordinates
* specify the new locations of each corner of the original bounding
* box. By specifying these values, any affine transformation
* (rotation, scaling, translation) can be affected. Additionally,
* these values can be specified such that the resulting transformed
* drawable will appear to have been projected via a perspective
* transform.
*
* Returns: The newly mapped drawable.
