This function copies a node into the scene graph if it has children. If yes, a new scene object
is created for the import node and the node's meshes are copied over. If not, no object is created.
Potential child objects will be added to the old targetParent, but there transformation will be correct
in respect to the global space. This function also works great in filtering the bone nodes - nodes
in respect to the global space. This function also works great in filtering the bone nodes - nodes
that form the bone hierarchy for another mesh/node, but don't have any mesh themselfes.

Example to convert from an Assimp material to a Direct3D 9 material for use with the fixed
function pipeline. Textures are not handled, only colors and the specular power:
@code

// if the material property is not existing, the passed color pointer
