Just did a little test with the back.png file - see attached it shows in 
black and white if it is NOT enabled.

However here stops the good news, I can't figure out what needs to be 
changed in matplotlib to get the same result.  Hacked "_load_bitmap2" 
which used the "png" file but then I get the normal image instead of the 
black and white one.

I'll keep looking, but if anyone has an idea it will be very welcome.

See you
