5762 order, leaving input focus unchanged. This is reasonable behavior
5763 on X where the usual policy is point-to-focus. However, this
5764 behavior would be very odd on Windows where the usual policy is
5767 On X, if the mouse happens to be over the raised frame, it gets
5768 input focus anyway (so the window with focus will never be
5769 completely obscured) - if not, then just moving the mouse over it
5770 is sufficient to give it focus. On Windows, the user must actually
5771 click on the frame (preferably the title bar so as not to move
5772 point), which is more awkward. Also, no other Windows program
5773 raises a window to the top but leaves another window (possibly now
5774 completely obscured) with input focus.
5776 Because there is a system setting on Windows that allows the user
5777 to choose the point to focus policy, we make the strict semantics
5778 optional, but by default we grab focus when raising. */
