Pango alignment versus wrapping

[Phil Wolff <adiabat centurylink net>]

Pango::Layout will display text in a Gtk::Label with PANGO_ALIGN_LEFT 
alignment as long as is_wrapped() returns FALSE. When something causes 
wrapping to occur, Pango::Layout then displays the text as though 
PANGO_ALIGN_CENTER had been requested, even though get_alignment() 
continues to return PANGO_ALIGN_LEFT.

Is this a feature or a bug?

If it’s a feature, is there a way to override it, so that 
PANGO_ALIGN_LEFT remains in effect?
