 The old way of removing a parent theme's templates (as documented
 [http://wordpress.org/support/topic/removing-page-template-from-child-
 theme?replies=3 here], [http://wordpress.stackexchange.com/questions/54054
 /how-to-remove-a-parent-theme-template-from-quick-edit here], and
 [http://stackoverflow.com/questions/9411612/wordpress-hiding-or-removing-
 parent-themes-templates here]) broke with the big theme-handling rewrite
 in 3.4.

 The primary use case of a new filter would be to allow a child theme to
 remove or rename a parent theme page template in the Dashboard. It's
 possible that part of the `get_page_templates()` function might have to be
 tweaked to allow for the scenario where one or more pages is using a
 template that no longer "exists," but I'm not sure.

 Hopefully this is as simple as adding `apply_filters( 'page_templates',
 $page_templates );` somewhere in
 [http://core.trac.wordpress.org/browser/trunk/wp-includes/class-wp-
 theme.php#L920 class-wp-theme.php].
