<p>This function is similar to a combination of <code class="function">clutter_actor_get_transformed_position()</code>,
and <code class="function">clutter_actor_get_transformed_size()</code>, but unlike
<code class="function">clutter_actor_get_transformed_size()</code>, it always returns a transform
of the current allocation, while <code class="function">clutter_actor_get_transformed_size()</code> returns
bad values (the transform of the requested size) if a relayout has been
queued.</p>
<p>This function is more convenient to use than
<code class="function">clutter_actor_get_abs_allocation_vertices()</code> if no transformation is in effect
and also works around limitations in the GJS binding of arrays.</p>
