Window manager decorations

[山本和彦]

Hello,

I'm suffering from the recent change, probably the one below:

        * xterm.c (x_set_offset): Take window manager decorations
        into account.

Consider the following code:
        (modify-frame-parameters (selected-frame) '((top . 0))

There are two kinds of window managers.

        Type A: does not adjust the height of a window title bar
                e.g. enlightment
        Type B: adjust the height of a window title bar
                e.g. window maker

Before the change:
        Type A: the title bar is hidden over the top of screen.
        Type B: the title bar lays just on the top of screen.

After the change:
        Type A: the title bar lays just on the top of screen.
        Type B: A space whose height is the same of the title bar 
                created between the top of screen and the title bar.

Thus, this change is kind to Type A but not friendly to Type B.

I'd would like to have a method to cancel the adjustment by Emacs.
