<p>The location and size of a rectangle.</p>
<p>The width and height of a <a class="link" href="clutter-Base-geometric-types.html#ClutterRect"><span class="type">ClutterRect</span></a> can be negative; Clutter considers
a rectangle with an origin of [ 0.0, 0.0 ] and a size of [ 10.0, 10.0 ] to
be equivalent to a rectangle with origin of [ 10.0, 10.0 ] and size of
[ -10.0, -10.0 ].</p>
<p>Application code can normalize rectangles using <a class="link" href="clutter-Base-geometric-types.html#clutter-rect-normalize" title="clutter_rect_normalize ()"><code class="function">clutter_rect_normalize()</code></a>:
this function will ensure that the width and height of a <a class="link" href="clutter-Base-geometric-types.html#ClutterRect"><span class="type">ClutterRect</span></a> are
positive values. All functions taking a <a class="link" href="clutter-Base-geometric-types.html#ClutterRect"><span class="type">ClutterRect</span></a> as an argument will
implicitly normalize it before computing eventual results. For this reason
it is safer to access the contents of a <a class="link" href="clutter-Base-geometric-types.html#ClutterRect"><span class="type">ClutterRect</span></a> by using the provided
