Exact control of window size/position is something that's not easily
achieved in X. The client app just suggests to the window manager its
desired size, but it's not guaranteed to get it. See

I talked to Ian about this, and we have an idea. You can tell the WM to
leave its hands completely off a window (via override_redirect). That way
you gain full control over the window, you can even place it over the
"always on top" windows like taskbar etc. However, you loose all the
convenient functionality the WM provides, like focus assignment and color
