I then tried displaying the data without draping it, the points where
excluded as expected, so it's seems the problem is with drape (or rather
strange). I resolved the problem by using compute on the colour component,
which did the trick.
BTW, it's quite annoying when I close a DX program my windowmanager
crashes (WindowMaker 0.65.0 on XFree86 4.1.0 running on Linux).
