/* --------------------------
* p_create_corpus_layer
* --------------------------
* create the corpus layer that builds the reference pattern
* for the resynthesizer call. The reference pattern is built
* as duplicate of the original image reduced to the area around the current selection.
* (grown by corpus_border_radius)
* Note that the duplicate image has a selection, that includes the gorwn area
* around the orignal selection, but EXCLUDES the original selection
* (that is the area holding the object that has to be replaced
* by pattern of the surrounding area)
* returns the layer_id of the reference pattern.
