Comment (by ryan):

 Move layout column setup into render_screen_meta(). Use add_option(
 'num_columns' ) and get_option( 'num_columns' ) for setting and getting
 the user selected number of columns. Retain the screen_layout_columns
 global for back compat. Switch admin screens from the global to
 get_option().
