Bug 316087 - Resizing columns is chaotic
* gtk/gtktreeprivate.h: add new member fields.
* gtk/gtktreeview.c (gtk_tree_view_init), (validate_row): set post
validation flag,
(gtk_tree_view_size_allocate_columns): rework the size allocation
mechanism to only recalculate the expand values if the width of the
widget, content or the column configuration has changed,
(gtk_tree_view_size_allocate): move call to size_allocate_columns()
to before the adjustment updates so the proper width is used after
we updated it,
(gtk_tree_view_button_press), (gtk_tree_view_motion_resize_column):
use the column width minus the expand value for the resized width,
(gtk_tree_view_move_column_after): update call to
gtk_tree_view_size_allocate_columns().
* gtk/gtktreeviewcolumn.c (gtk_tree_view_column_set_expand): set use
resized width to FALSE.
* tests/Makefile.am:
* tests/testtreecolumnsizing.c: new interactive test program
for testing column resizing with different column configurations.
