This adds a basic library and support to dtsession and dtlogin to support Xinerama/Twinview, where multimple monitors are used to make up an X11 screen. The main goal here is to draw dialogs and such centered on a monitor, rather than spread out over multiple monitors. Might need to add sorting - as on my test system, what I would consider monitor 0, appears to actually be monitor 1. So a sort might need to be added to sort the screens according to increasing x and y offsets so it make sense to a user. Also, this library is built statically and not documented. Maybe it could be 'filled' out and refactored/redesigned in the futre if need be and suppoerted. It is enabled via a define, CDE_USEXINERAMA in site.def. It's a very simple lib, so I do not expect any issues with the BSD's - it should build and work fine, assuming your X server has the XINERAMA extension, which I think pretty much all of them do at this point.
