I think IDL does not support 16 bpp in any Unix version, so you will
definitely have to change to 8 bpp (with all color flashing problems
etc.) or to 24 bpp. With most graphics cards & resolutions, if you can
use 16 bpp, you can use 24 bpp as well. I use 16 bpp per default
(because my 24 bpp X server has many bugs) - and when I need IDL graphics,
I open another virtual terminal with 24 bpp with a command like
(this is for Linux):
X -query localhost -bpp 24 :1
IDL not supporting 16 bpp is *almost* a reason to dump it.
