Trevor Davenport f869f3cc76 modesetting: Fix invalid identity CTM on 32-bit.
On 32-bit, the shifts used to initialized the identity CTM overflow and
result in zero instead of the intended 1.  This results in a broken
display (on at least i915) when using the modesetting xorg driver.

Fix the invalid CTM by using ULL suffix on the shifts.

X Server

The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.

Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
