commit f284ad33fe00ed3d9cdb5b14040e7d282b13ee38

xfce-panel-plugin: added a virtual method xfce_panel_plugin_lenght_adjust
This method is to be used for asking shrinking plugins to adjust their
length based on the proposed length of the allocation area. This can be used
for example to limit their minimum sizes or implement more complex sizing
policies (such as non-continuous resizing during shrinking). A default noop
implementation is provided in the xfce-panel-plugin so the change should be
transparent to other plugins.
TODO add support for the same functionality in the external plugins.
