+%Magnum provides a set of simple shapes for collision detection, similarly to
+what is found in many other collision detection libraries. Additionally some
+shapes are provided in inverted form -- e.g. inverted box detects collisions on
+outside instead of inside, which might be useful for example to create bounds
+around platformer game level.
