Intermediate checkin of improved visual selection mechanism. Intended

to fix problems on X11 platforms including inability to choose a
visual and lack of multi-head support, as well as to improve the
selection algorithm on all platforms by allowing the window system to
provide a recommended visual selection. Lays the groundwork for
full-scene antialiasing and multihead support on multiple platforms.
