/*
* The gtk2 vte terminal widget seriously messes up the window resize
* for some reason. You basically can't make the qemu window smaller
* any more because the toplevel window geoemtry hints are overridden.
*
* Workaround that by hiding all vte widgets, except the one in the
* current tab.
*
* Luckily everything works smooth in gtk3.
