Yes, but the point is that, unless the metafile is a bitmap in these case,=
 it 
will not look at all like what you see onscreen.  Surely something which 
fundamentally changes the appearance of a graphic for the worse is=
 unacceptable 
behavior.  But for many other graphics, as you've discovered, metafile does=
 
preserve a vector representation.  It is superior to bitmap in some cases, 
equivalent in others.  The best compromise we could come up with for file 
formats which were designed around 1990 and 1995 respectively (for Windows=
 and 
Enhanced variants of the metafile format...my dates might be slightly off,=
 but 
are about right).

There was a sea change in the quality of graphics between 5.2 and 7.  If=
 you're 
willing to live with the graphics technology that we created in the 1990s,=
 you 
can run it in version 7 by evaluating...

<< Version5`Graphics`

before evaluating your plot commands.  You'll get static, non-interactive 
graphics (the first thing you'll notice is that you can't rotate the 3D 
graphics) with all of the best features we designed in the 90s, and they=
 live 
completely within the limitations of the metafile format.

Some of the newer plotting commands may not produce graphics correctly in=
 this 
mode, but all of the basic functionality will probably work fine.
