Title: layout.js:  Ignore panel heights for metawindow position calculations

when in fullscreen mode.

This caused undesirable behavior in some applications that use tooltips
to display information/controls (like VLC) when in fullscreen mode.

The panel height was still being taken into account initially when
figuring out the useable screen area.
