A bounding box in 2D space.
<p>
In order to operate correctly, this bounding box assumes that all values entered or compared against lie within the range (-<a class="el" href="group__geom__utils.html#g5acebae804990b2e4fc030a61c662e48" title="The maximum value that a coordinate in the bounding box can use.">CS_BOUNDINGBOX_MAXVALUE</a>, <a class="el" href="group__geom__utils.html#g5acebae804990b2e4fc030a61c662e48" title="The maximum value that a coordinate in the bounding box can use.">CS_BOUNDINGBOX_MAXVALUE</a>).
