Thanks for the information.  I asked because I was getting conflicting information.  I did attempt to find an answer with Google.  I'm sorry if I offended you.

    The MacPorts version of Mesa is 17.1.6. It took roughly 30 second for me 
    to find this page: https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.mesa3d.org%2Frelnotes%2F17.1.6.html&data=02%7C01%7Cstephen.langer%40nist.gov%7Cb089a5bbbf384a5ca6bb08d5652c5d01%7C2ab5d82fd8fa4797a93e054655c61dec%7C1%7C0%7C636526163576545449&sdata=ai86TDzzmiXRIduisritq%2BthkgCMRHtjX5JATnrTv3A%3D&reserved=0

    Read the second paragraph in the first section.

    I am not familiar with this particular software combination (or the 
    version widgetry of OpenGL) but based on that paragraph and the error 
    message, it seems to me that this is either a vtk bug or a limitation of 
    the underlying driver.
