-  Dirty hacks because iOS is weird and decided to define both SCNVector3's and SCNVector4's objCType as "t". However @encode(SCNVector3) and @encode(SCNVector4) both return the proper definition ("{SCNVector3=fff}" and "{SCNVector4=ffff}" respectively)
- 
-  [[NSValue valueWithSCNVector3:SCNVector3Make(0.0, 0.0, 0.0)] objcType] returns "t", whereas it should return "{SCNVector3=fff}".
