Panel plugins have a fixed size in trunk

Indeed, there does seem to be some weird things going on with the size
setting after a reorientation.  It seems the panel plugin is set to an
explicit size, as if a size-changed handler returned FALSE, and you
need to set the XfcePanelPlugin size, not just the widgets inside it,
to make it work.

I changed trunk last week to only set the panel height (or width if
vertical) and leave the plugins themselves untouched (as long as they
return TRUE from their size-changed handler).  Unfortunately this
doesn't seem to help much.
