Marc Mutz d86e101d1b xcb: fix (negative) coordinate handling 
For some reason, XCB accepts positions as unsigned
integers, even though the X protocol explicitly
allows negative values (windows overlapping the
left/top screen border).

After discussion with Samuel and Laszlo, use a
reinterpret_cast to convert from the signed
representation to the unsigned one.

I also extended the clipping of the extents to
the position. I guess if X can't handle widths
beyond XCOORD_MAX, it won't be happy with
x-coordinates exceeding that limit, either.
