% Bugfix: We changed \@setheadheight and \@setfootheight to fix a bug
% that was introduced by the bugfix in version 2.306beta, 2009/03/28:
% If the second page has a different \textheight (because of a change
% in either headheight or footheight between pages 1 and 2), then page
% 2 would use the \textheight of page 1. Pages 3 and beyond would get
% the correct \textheight. The original version of this set \@colroom
% and \vsize to the new \textheight, but that had a bug in that if a
% float appeared at the top of a page, there would be no notice taken
