To invert an XImage, I can think of creating a pixmap of same size and
depth, copying the image (with XPutImage and GXcopyInverted) into the 
pixmap, and retrieving the image back from the pixmap (XGetImage). 

Is this the right way?  Does it mean all graphics operations on images
have to go through a pixmap?

Thanks.
