frame-pixel-width is correct in the Carbon port.

frame-pixel-height returns a value that is too low, as it doesn't  
contain the title bar. This seems consistent across the platforms,  
from what I hear, but it is annoying nevertheless.

The documentation reads:

"This counts only the height available for text lines, not menu bars  
on window-system Emacs frames."

If you count the tool-bar as "available for text lines", and the title  
bar as part of the non-existant menu bar (on my system), then that is  
indeed correct.

So, either way, it would be useful to have the full height of a frame.  
Consider that (frame-parameter nil 'top) returns the position of the  
top edge, and not the y ordinate of the location where text could  
potentially be displayed in the frame.
