IIRC, it's a hack because neither x nor y is usually -32000, so those are flag
values instead of fixed actual values. You have enough physical screens laid
out in a line it's possible (16 1080p + a 1280 wide one), but still unlikely on
one system given it would take multiple video cards to drive that many. The
desktop as a decorated window hides the resize frame and title bar by
positioning outside the effective area of a multiple screen layout and using a
width and height that just encompasses the layout in Display Properties as the
client area dimensions, with (0,0) of the viewports being one of the corners of
the primary screen's client area. This forces at least one position coordinate
to be negative by at least the width of the resize frame. I forget whether this
is documented in the DDK or SDK, sorry, and which edition.

Hello,
Why is this a hack?
Thanks,
