Hi Carlos,

No, I can't get the behavior that you want, and that Gimp achieves.

I think Murray is right in suspecting a problem with GtkToolPalette's
size request code.

I suspect an error in GtkToolItemGroup, in
gtk_tool_item_group_size_request(). It seems it requests the same size
whether the GtkToolItemGroup is expanded or collapsed. But I'm not sure.
The size request and size allocation code is quite complex.
