* we map the 4th Windows color (invert the bits on the screen)
* to black and an additional white bit on an other place
* (+1,+1). This require some boolean arithmetic:
*
* Windows | X11
* And Xor Result | Bits Mask Result
* 0 0 black | 0 1 background
* 0 1 white | 1 1 foreground
* 1 0 no change | X 0 no change
* 1 1 inverted | 0 1 background
*
* which gives:
* Bits = not 'And' and 'Xor' or 'And2' and 'Xor2'
* Mask = not 'And' or 'Xor' or 'And2' and 'Xor2'
*
* FIXME: apparently some servers do support 'inverted' color.
* I don't know if it's correct per the X spec, but maybe we
* ought to take advantage of it. -- AJ
