Panel HIG: rtl layouts

[Diego Ongaro]

On the panel HIG ( http://wiki.xfce.org/panel-hig ), I proposed that
Class B (Button) plugins such as xfdesktop's menu and the places
plugin should display the icon/image on the left and the label on the
right (for horizontal panels). Fabian responded that users with rtl
languages such as Arabic would probably want the opposite order.

Would users of rtl languages want the opposite order? What about on
vertical panels?

How could a plugin tell (in code) if it's being used with an rtl language?

Does GTK provide any support for this, for example by packing things
into boxes in the opposite order?

Thanks,
Diego
