* 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.
