Fabiano Fidêncio 4de3379f34 Update geometry when enabling/disabling displays 
_update_displays_geometry() must be called every time a display is
enabled/disabled, avoiding gaps (when a display is disabled) or overlaps
(when a display is enabled) between the monitors.

This is what happens when we have 3 displays enabled (each one
represented by: width x height + x position + y position) ...

  Display #0       Display #1         Display #2
 +---------+      +----------+       +---------+
 |         |      |          |       |         |
 |         |      |          |       |         |
 |         |      |          |       |         |
 |         |      |          |       |         |
 |         |      |          |       |         |
 |         |      |          |       |         |
 +---------+      +----------+       +---------+
(680x804+0+0)   (504x804+680+0)    (408x804+1184+0)

Whether the Display #1 is disable, a message will be sent down to the
vdagent, representing the new arrangement of the monitors:

  Display #0     Display #2
 +---------+     +---------+
 |         |     |         |
 |         |     |         |
 |         |     |         |
 |         |     |         |
 |         |     |         |
 |         |     |         |
 +---------+     +---------+
(680x804+0+0)  (408x804+1184+0)

However, taking a look on the x position, a gap can be identified as
Display #0 starts at position (0,0) and has 680 pixels of width. But
Display #1 only starts at position (1184, 0), leaving 504 pixels as a
gap. The proper message, however, should represent the following
arrangement ...

  Display #0       Display #2
 +---------+      +---------+
 |         |      |         |
 |         |      |         |
 |         |      |         |
 |         |      |         |
 |         |      |         |
 |         |      |         |
 +---------+      +---------+
(680x804+0+0)   (408x804+680+0)

... avoiding then gaps and overlaps.

  Virt Viewer
  ===========

Virt Viewer provides a graphical viewer for the guest OS
display. At this time is supports guest OS using the VNC
or SPICE protocols. Further protocols may be supported in
the future as user demand dicatates. The viewer can connect
directly to both local and remotely hosted guest OS, optionally
using SSL/TLS encryption.

Virt Viewer can be built with either GTK2 or GTK3, with the
default option currently being GTK2. The choice can be made
with:

   ./configure --with-gtk=3.0  (or =2.0)

Virt Viewer uses the GTK-VNC (>= 0.4.3) widget to provide a
display of the VNC protocol, which is available from

  http://gtk-vnc.sourceforge.net/

Virt Viewer uses the SPICE-GTK (>= 0.22) widget to provide a
display of the SPICE protocol, which is available from:

  http://spice-space.org/page/Spice-Gtk

Use of either SPICE-GTK or GTK-VNC can be disabled at time
of configure, with --without-gtk-vnc or --without-spice-gtk
respectively.

Virt Viewer uses libvirt to lookup information about the
guest OS display. This is available from

  http://libvirt.org/

Further information about the Virt Viewer application can be
found on the Virt Manager website:

  http://virt-manager.org/

Feedback should be directed to the mailing list at
