minor titlebar edge cleanup

Browse source 
remove the ShadowEngine... it is just too slow and even makes e.g. kmail feel
slower when dragging messages over the folder list. have a bogus shadow
instead (various drawText calls with blended colors) which also looks quite nice and
is twice as fast. Still no kwin decoration seems to feel as fast as metacity when it
comes to caption changes such as in the kmail example... This is something that should
be looked into IMHO.
