@brief Solid 3D icosphere
@param subdivisions      Number of subdivisions

Sphere with radius @cpp 1.0f @ce. Indexed @ref MeshPrimitive::Triangles with
normals.

@image html primitives-icospheresolid.png width=256px

The @p subdivisions parameter describes how many times is each icosphere
triangle subdivided, recursively. Specifying @cpp 0 @ce will result in an
icosphere with 20 faces, saying @cpp 1 @ce will result in an icosphere with 80
faces (each triangle subdivided into four smaller), saying @cpp 2 @ce will
result in 320 faces and so on. In particular, this is different from the
`subdivisions` parameter in @ref grid3DSolid() or @ref grid3DWireframe().
@see @ref uvSphereSolid(), @ref uvSphereWireframe()
