It turned out that `x_set_offset' was called with `f->left_pos' and
`f->top_pos' as arguments which have to be updated after the frame was
created.  The following patch works for me:

An issue left is that the bottom of the frame may be covered by the
task bar if it is placed too low on the screen.  Does anybody know why
`CreateWindow' or the other functions involved do not take care of
this?
