The Athena Label Widget, techincally, only takes BITMAPS and not PIXMAPS.

There is a distinction.  A BITMAP contains 1's and 0's.  A PIXMAP contains
Pixel Values.  When the Athena label widget tries to write out a BITMAP,
it maps 1's and 0's to foreground and background.

You had already permuted these values with XCreatePixmapFromBitmapData.
You should NOT be using this routine for this purpose, you should be
using XCreateBitmapFromData.

The Athena Label widget actually tries it best with a pixmap by testing
its depth.  If depth 1 it assumes a BITMAP, otherwise, it assumes a PIXMAP.

If you were on a multi-plane device, your problem would mysteriously disappear.
