sub edit_cut {

If there is a selection in the image, then the area specified by the
selection is cut from the specified drawable and placed in an internal
GIMP edit buffer. It can subsequently be retrieved using the
gimp_edit_paste() command. If there is no selection, then the
specified drawable will be removed and its contents stored in the
internal GIMP edit buffer. This procedure will fail if the selected area
lies completely outside the bounds of the current drawable and there is
nothing to copy from.

This procedure pastes a copy of the internal GIMP edit buffer to the
specified drawable. The GIMP edit buffer will be empty unless a call
was previously made to either gimp_edit_cut() or gimp_edit_copy(). The
"paste_into" option specifies whether to clear the current image
selection, or to paste the buffer "behind" the selection. This allows
the selection to act as a mask for the pasted buffer. Anywhere that
the selection mask is non-zero, the pasted buffer will show
through. The pasted buffer will be a new layer in the image which is
designated as the image floating selection. If the image has a
floating selection at the time of pasting, the old floating selection
will be anchored to its drawable before the new floating selection is
added. This procedure returns the new floating layer. The resulting
floating selection will already be attached to the specified drawable,
and a subsequent call to floating_sel_attach is not needed.
