This procedure makes the item behave like a typical raster layer.
Note that the source information (text contents and properties for a
text layer, source file for a link layer, path and render properties for
a vector layer, etc.) are not actually discarded, and it is possible to
retrieve the original behavior with [method@Gimp.Rasterizable.restore].

Restore the information making the item non-destructive, such as text
contents and properties of a text layer, source file of a link layer,
path and render properties of a vector layer, etc.
This item won't behave anymore like a raster item. In particular, it
will prevent direct modification of its pixels and will be rendered when
its properties are updated.

$help = <<'HELP';
This procedure returns %TRUE if the specified @item has been previously
rasterized. In this case, you should treat this @item as the generic
raster variant.
For instance, a [class@Gimp.TextLayer] object implements the
%GimpRasterizable interface. If a text layer instance were to return
%TRUE, you should only consider its rendering as returned by
[method@Gimp.Drawable.get_buffer].
On the other hand, if this returned %FALSE, depending on your intents,
you may prefer to use the text contents and its properties with the
various procedures provided by the [class@Gimp.TextLayer] class interface.
