Have found that default-frame-alist much trickier to use.  If I set
(top . 21) (left . 21) the frame might get placed on a different 
monitor than from the monitor emacs was called.

Have also done a frame-inhibit-implied-resize, this fixes the top-bottom centering
but not the left-right centering.  Looks as if we need a new function that ensures
the frame is centered.

   (setq initial-frame-alist '((width . 75) (height . 21)))

   (setq frame-inhibit-implied-resize t)

   (set-face-attribute 'default nil :height 160 :weight 'bold)

   (setq frame-inhibit-implied-resize nil)
