More of the window properties are checked using simple
window property handlers. The ones which remain don't
actually look up the new value in the ordinary way, and
so are a little trickier to merge. Added an "initial"
flag to be on the safe side that the behaviour is the
same as before (so we don't do things when a window's
first mapped that we only used to do when a property
changed). Partial fix for bug #549886.
