Ah, I see. A misunderstanding. On w32 the window manager can maximize
a window, but it can't just maximize the height and not the width.
"Maximized" on w32 is a state where the window is not moveable and the
window occupies the working area of the display (taking into account
how the taskbars are configured).

Some misunderstanding. I told the API:s for getting the size of the work area.

I do not understand what you mean. I gave references to the API:s to
do exactly this. What is unclear?
