  The VMD near/far clipping planes only apply to OpenGL renderings, and have
no effect on POV-Ray, Tachyon, or any of the other renderers. In order to
make this more clear, I plan to redesign the "display settings" menu
in a future version of VMD, drawing a box around OpenGL-specific items
such as near/far clipping planes, much like had been done for the
settings that currently only apply to renderings via ray tracers
(e.g. shadows, and ambient occlusion lighting).
