> Can a Window Manager obtain the border pixel of a client?

Nope.  The server converts the background and border pixmaps (pixels are
basically a shorthand for solid-color pixmap) to whatever internal
representation is most efficient, and is not required to bump the reference
count of the PIXMAP data structure.  Since the client is allowed to immediately
free the pixmap after creating the window (see CreateWindow in the Protocol
document), there might not be a pixmap corresponding to the indicated id (or
worse yet, it could be the wrong one).
