/*
* RiTypesHelper.h offers support for modern c++ programming conveniences.
* The idea is that we can 'alias' the c++ classes to plain-old-data (POD)
* types in the standard typedefs (above).
*
* Here's an example programming idiom (for the simple scalar case):
*
*  RtPoint op = {1,2,3}; // POD
*  RtPoint3 &np = reinterpret_cast(RtPoint3&)(op); // RtPoint3 is a c++ type
*
*  Note that the C++ types (RtPoint3 is this example) will have different
*  functional-call and initialization semantics.  Pass-by-value for RtPoint
*  is implemented as a pointer reference while RtPoint3 is struct copy.
*  For highest performance code (or to match traditional Ri semantics) it
*  may be advised to pass RtPoint3 by reference. Or continue to rely on
*  POD for transport.
*
*  Currently RiTypesHelper.h offers these classes with the obvious
*  operator overrides:
*
*  RtPoint2, RtVector2 have no "C" equivalent
*  RtPoint3, RtVector3, RtNormal3 match RtPoint, RtVector and RtNormal
*  RtColorRGB matches RtColor
*  RtMatrix44 matches RtMatrix
*
