How does one determine a given window's background pixel value (assuming that it's a single pixel value, not a pixmap)? The documentation seems to indicate that this information is not available--there is a background-pixel-value field in the set-window-attributes structure, but there is no such field in the get-window-attributes structure. ??? I'm using CLX, so I'd be interested in hearing about the CLX way to do this, but I don't even see a way of doing this with straight Xlib (short of keeping track of the background value myself, which seems silly because the system has to know the background value in order to repaint it).
