To set the background color, my IMDISP procedure uses code similar to
the following:

x = [-0.01, 1.01, 1.01, -0.01, -0.01]
y = [-0.01, -0.01, 1.01, 1.01, -0.01]
polyfill, x, y, /normal, color=background

where the variable "background" is an index in the color table. This is
the only way I know of to reliably set the background color on all IDL
direct graphics devices. The source for IMDISP is available at
