I find I can avoid this (still on my 8-bit display) by explicitly
setting `topShadowPixel' and `bottomShadowPixel' resources.

So emacs could just do the shadow color allocation for the scroll-bar
itself (it already does this for the scroll-bar fg/bg colors, so the
code should be very simple), since it can do a better job of it.  This
is also good because the same highlight color calculation routines can
be used as other 3d objects in emacs, so the resulting colors will look
more consistent.
