shapes. It doesn't work in the case of spheres (used by projectiles):
resulting shape is malformed. It can also leads to this error which
makes the debug drawer non-working till game restart:
CullVisitor::apply(Geode&) detected NaN,
depth=nan, center=(nan nan nan),

Avoid this issue by using osg::Sphere
While here, remove an unused function. We don't use Bullet's solver so
we never have any contact points (in Bullet parlance).
