This is part of collection of simple utility classes for GL only in
TGLUtil.h/cxx. These provide const and non-const accessors Arr() &
CArr() to a GL compatible internal field - so can be used directly
with OpenGL C API calls - which TVector3 etc cannot (easily).
They are not intended to be fully featured just provide minimum
required.
