FYI - You can use (x-display-pixel-width) to pick up the `1280' value
automatically, so it is correct regardless of the current display. In the case
of yours, it will be 1280.
Not really, as one monitor will be to the left of the other, and the
other will to be to the right of the first. You can't generalize - some
people will configure their main monitor to the left, others to the
right, and still others will configure them above, below or even
diagonally. The values for left and top need to be customized for the
particular setup that the user has.
