Re: [ROOT] Where did 8 bit X3D support go?

But... that's not what happens.  Can you, or someone else, check it on an
old display?  Nothing shows up in color.

There are a few X3D changes listed in the Release Notes:
2001-05-16 18:23  rdm

        * x11/inc/TGX11.h, x11/src/TGX11.cxx, x3d/inc/x3d.h,
        x3d/src/x3d.c:
        added support for TrueColor X11 servers with bgr instead of rgb
        (or any other permutation for that matter), like eXceed.

2001-05-11 19:20  rdm

        * x11/inc/TGX11.h, x11/src/GX11Gui.cxx, x11/src/TGX11.cxx,
        x11ttf/src/TGX11TTF.cxx, x3d/src/x3d.c:
        new methods AllocColor() and QueryColors() that reduce the
        expensive X11 round-trip commands XAllocColor and XQueryColor in
        case of TrueColor displays.

2001-05-08 20:11  rdm

        * x3d/: inc/x3d.h, src/x3d.c:
        finally fixed x3d for 15 and 16 bit true color visuals.

I think that th 8-bit support was lost somewhere in there.
