I do notice some differences, but as Andreas Schwab said, the bug(s)
still remain(s).  When I tested this prior to the unicode merge, I just
used the default font for my system with emacs -Q.  Now I have tried a
few different fonts and pixel sizes on the builds I have (using
set-frame-font for the pre-unicode-merge builds), and I find a variety
of behaviors with respect to maximizing and restoring either
horizontally (mouse-3) or vertically (mouse-2).  But I haven't found any
combinations that allows restoring after maximizing with mouse-1 (both
dimensions simultaneously) (and maximizing with mouse-1 is not
"maximal", as previously detailed; this is also the case where
restoration fails in one dimension).  Also, in each case where mouse-3
is restorable but mouse-2 is not (i.e. horizontally but not vertically),
restoration only works if the frame is not vertically maximized.

Here is a summary of the tests I have made (the latest build contains
your changes):

======================================================================
Frame maximization tests in KDE: 
mouse-1 maximizes both vertically and horizontally, mouse-2 only
vertically, mouse-3 only horizontally
+ => restoring from maximized succeeds, - => restoring fails

The pixel sizes with the Times fonts of the 2008-03-03 build are larger
than the sizes with corresponding fonts of the 2008-02-21 build,
e.g. Times-12 of the former is the same size as Times-14 of the latter.
