TreeViewColumn resizing #63732

[Detlef Reichl <detlef reichl arcormail de>]

the TreeViewColumn resizing code doesn't considers the
tree_view->priv->hadjustment. so if the tree_view is in a scrolled
window that is scrolled to the left, the column jumps away... (sorry,
uggly expanation)

attached the patch to fix this


have a nice day
