Xfdesktop 4.7.0
---------------
* Depend on exo-1 (0.5).
* Drop dependency on libxfcegui4 and use libxfce4ui.
* Remove the menu panel plugin, this is now included in the panel.
* Remove various .desktop files for the menu, those are now
included in the packages they belong to (exo, utils and session).
* Remove the .directory files, those are now shipped with Garcon.
* Drop the libxfce4menu dependency and use Garcon.
* Build documentation during make dist.
* Allow DnD to image list in settings dialog (bug 4337).
* Refactor drawing routines in XfdesktopIconView to remove most
flicker and most if not all repaint glitches.
* Use cairo to draw the rounded text label background instead of
the hacky PNG composition method.
* Make the text label corner roundness configurable via a gtkrc
style property.
* Call to org.xfce.FileManager.DisplayFileProperties() for the
full-featured file properties dialog before falling back to our
own (bug 5622).
