class TGLSelectionBuffer


TGLVertex3

3 component (x/y/z) vertex class

 This is part of collection of utility classes for GL 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. They are not intended to be fully featured just provide
minimum required.
