    this class was originally written as a demo on how an interface to
    a c graphics library could be implemented. In the mean time, it has become
    quite complete ...

    It provides an interface to either a real GL (on SGI workstations)
    or a simulated VGL (i.e. GL-light; low nicotine).
    The GL simulation is derived from the PD vogl library, with slight
    modifictions to support multiple GL views.

    Most of the hard work was done by Jeff (thanks indeed) ...


    Some notes:

    I do not really know what most of these functions do - for more
    detail, see the GL man pages (on SGI) or the doc provided with VGL.

    The interface offered here provides a very very low level (i.e one-to-one)
    interface to GL functions. More high-level stuff is required, to make
    3D drawing be more object-oriented. 
    (see a bit of this in 'clients/IRIS-specials')

    Some functions are duplicated, Jeff and I developed those in parallel -
    for now, both will remain - finally they will be merged and duplicates removed ...
    (examples are makeobj and makeObject).

    Also, in a hurry to implement all those methods, many do no or only
    limited argument checking - make certain, that you pass the correct
    arguments.

    There might be some confusion in the v3[sifd] functions: basically they
    all do the same, and could be mapped onto one st-method (such as vertex3).
    However, the C-functions expect different argument types - I dont know if
    one or another of these functions suffers from any performance penalties.
    Therefore, I leave the direct 1-to-1 mapping; GL experts might know more
    about this (I use v3f in all of my code).

    written june 93 by claus
    VGL stuff dec 93
    many many additions jan 94 by Jeff McAffer <jeff@is.s.u-tokyo.ac.jp>

    Since this is a demo (consider it a free add-on goody) there is 
    *** NO WARRANTY ** for this.

    Notice: this should be rewritten to use the openGL library functions
    (actually, to not loose the VGL interface, another OpenGLWorkstation
     class should be written)
