Notes:
1. T/T & F/F above refer to the
gtk_box_pack_start() 'expand'/'fill' args
used to pack the widget into the enclosing GtkBox.
2. The 'Alignment' widget is actually internal to
the GtkFileChooser widget.
Gtk3: Expand/Fill effect
Vertical
(file_chooser): expand/fills.
main_hb does not expand/fill [explicitly set via vexpand = FALSE].
btn_row does not expand/fill.
So: vertical resize (drog lower edge down).
expands (file_chooser) but leaves others as is.
Also: grid rows are "vexpand' so grid
vertically epands/fills in main_hb.
That is: it will be the same height as
the main_vb.
Since vexpand is "inherited upwards", main_hb vexpand set to FALSE
to prevent vertical expansion of same.
Horizontal
(file_chooser) & btn_row: expand/fill.
main_vb & grid do not expand.
So: horizontal resize (drag right edge to the right)
expands all but the "extra widget".
