The flag is implemented at the plugin level (with a default set in the 
plugin base class). But the actual layout is currently being done by the 
itembar object. So far I was following only existing patterns - similar 
plugin flags "expand", "shrink" already exist and are handled the same way.

The exact size (with pixel correction) is unknown because the plugin 
doesn't have any information on the exact location in the panel. Also, 
this size would have to be updated every on the panel size (width) 
change, which means (not sure about that) more events hit the itembar.

If we want to overload the plugin size, then I'd rather set the 
requested size to a constant size like (0, 0) or (1, 1). But that's 
starts looking hacky.

Thanks.
