It seems the EventSystem.RaycastAll() returns hit results for elements that are partially onscreen, even when the raycast hit position is happening outside the window.

There are two new problems I see in our app which may be because of this fix:
(1) We navigate our app on Windows desktop by holding down the left mouse button and dragging the mouse. When we drag outside the window, the previous clamping behaviour gave more expected results. Rather than either clamping or locking to the last point in the window, why not do the "usual" thing and capture the mouse position, even outside the window? See Microsoft's SetCapture() and ReleaseCapture() functions. This would give correct behaviour AND fix the original problem.
(2) When running in the Editor, if I drag the mouse past the left side of the window, it suddenly acts as if it's on the far RIGHT of the window! So I'll be panning left and suddenly it will switch to panning fast right. Clearly this is a new bug. Only started doing this in 5.3.5, not in 5.3.4.
Thanks,
Rob.
