Description
The GimpRgnIterator functions provide a variety
of common ways to traverse a PixelRegion,
using a pre-defined function pointer per pixel.

Creates a new GimpRgnIterator for drawable. The GimpRunMode
parameter is ignored. Use gimp_rgn_iterator_free() to free thsi
iterator.

Returns : a newly allocated GimpRgnIterator.
