The problem here is that JavaScript doesn't have more than
one number type, and gjs tries to automatically guess what

something, it will use an integer, which will cause errors
in GLSL.

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.
