[virt-tools-list] [virt-manager][PATCH 0/4] Allow hiding window decorations and menu bar

[Povilas Kanapickas]

The screen estate used by the virt-manager itself in the console mode reduces
the amount of screen estate available to the VM. virt-manager currently supports
the fullscreen option to make maximum use of the available screen. Unfortunately,
this hides the OS taskbar, which makes this approach less usable for workflows
that need to use the taskbar, e.g. when switching between many different VMs at
the same time.

The PR introduces a "hide decorations" menu option. This option hides the menubar
and the OS window decorations of the VM viewer. Essentially, it's the fullscreen
option without actually going full screen, i.e. the window mechanics are still
preserved and the window can still be hidden, obscured and so on. This mode can
be turned off much like the fullscreen option - my moving mouse near the top edge
which shows the usual two-button box.

The PR also slightly changes how the "revealer" box works. In non-fullscreen mode
the assumption that it's easy to navigate to the exact top pixel of the window
no longer holds. So the eventbox is now a completely separate rectangle from the
revealer itself and thus can span much wider span of the window and be more than
a single pixel high. This way we don't grab mouse events from much larger area
than we want whenever the box with buttons is shown which would have been an
issue with the previous implementation if I just increased the width of the
eventbox.

Thanks!
