For your information there is a peculiar but designed interaction between the background colour and _default_ cmap1.
If you run example 16 with the background set to a light-coloured value, e.g., c/x16c -dev psc -o test.ps -bg fffff or c/x16c -dev psc -o test.ps -cmap0 cmap1_black_on_white.pal you get very different default cmap1 values than if you run with a black background colour. The result is independent of device driver. I originally thought this was some horrible bug, but it turns out the vertex logic used to set the _default_ cmap1 depends on the mean background colour by design. I wasted a lot of time on this today (including a binary search to "discover" that the effect was not there for -bg 7f7f7f but was there for -bg 808080) so I thought I should mention it here so that others don't waste their time trying to track down this "bug".
