This procedure flips the specified item. If a selection exists and the
item is a drawable, the portion of the drawable which lies under the
selection is cut from the drawable and made into a floating selection
which is then flipped. If auto_center is set to TRUE, the flip is
around the selection's center. Otherwise, the coordinate of the axis
needs to be specified. The return value is the ID of the flipped
item. If there was no selection or the item is not a drawable, this
will be equal to the item ID supplied as input.  Otherwise, this will
be the newly created and flipped drawable.

This procedure flips the specified item. If a selection exists and the
item is a drawable , the portion of the drawable which lies under the
selection is cut from the drawable and made into a floating selection

the flipped item. If there was no selection or the item is not a
drawable, this will be equal to the item ID supplied as input.
Otherwise, this will be the newly created and flipped drawable.

Perform a possibly non-affine transformation on the specified item.
BLURB

    $help = <<'HELP';
This procedure performs a possibly non-affine transformation on the
specified item by allowing the corners of the original bounding box to
be arbitrarily remapped to any values. The specified item is remapped
if no selection exists or it is not a drawable. However, if a
selection exists and the item is a drawable, 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 return value is the ID of the remapped item. If there
was no selection or the item is not a drawable, this will be equal to
the item 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 item will appear to
have been projected via a perspective transform.

This procedure scales the specified item. If a selection exists and
the item is a drawable, the portion of the drawable which lies under
the selection is cut from the drawable and made into a floating
selection which is then scaled by the specified amount. The return
value is the ID of the scaled item. If there was no selection or the
item is not a drawable, this will be equal to the item ID supplied as
input. Otherwise, this will be the newly created and scaled drawable.

This procedure shears the specified item. If a selection exists and
the item is a drawable, the portion of the drawable which lies under
the selection is cut from the drawable and made into a floating
selection which is then sheard by the specified amount. The return
value is the ID of the sheard item. If there was no selection or the
item is not a drawable, this will be equal to the item ID supplied as
input. Otherwise, this will be the newly created and sheard
drawable. The shear type parameter indicates whether the shear will be
applied horizontally or vertically. The magnitude can be either
positive or negative and indicates the extent (in pixels) to shear by.

sub item_transform_2d {

    $help = <<'HELP';
This procedure transforms the specified item. If a selection exists
and the item is a drawable, the portion of the drawable which lies
under the selection is cut from the drawable and made into a floating
selection which is then transformed. The transformation is done by
scaling the image by the x and y scale factors about the point
(source_x, source_y), then rotating around the same point, then
translating that point to the new position (dest_x, dest_y). The
return value is the ID of the rotated drawable. If there was no
selection or the item is not a drawable, this will be equal to the
item ID supplied as input. Otherwise, this will be the newly created
and transformed drawable.

This procedure transforms the specified item. If a selection exists
and the item is a drawable, the portion of the drawable which lies
under the selection is cut from the drawable and made into a floating
selection which is then transformed. The transformation is done by
