What do we need from other projects?

I believe an X extension is needed to completely solve bug 1410:

On windows, when dinput listens for relative mouse movement, it does
so without affecting the cursor's position. Wine implements relative
mouse movement by constantly recentering the cursor on the window that
requests it and watching it as it moves away from the center. In
exclusive mode, this rarely causes problems as that combination makes
it impossible to move the mouse on windows. Some apps request relative
mouse movement in nonexclusive mode and expect the user to move the
mouse normally (but the user can't because the mouse is always being
recentered). If wine didn't recenter the mouse, it wouldn't be able to
detect mouse input that would bring the mouse beyond the edge of the
screen (which windows can do).

Windows probably pulls this off by reading relative mouse movement
directly from the device, but I don't think wine developers want to go
that route. An X extension would be needed that can detect relative
mouse movement that does not generate absolute movement.
