Because (1) it's what other programs do, (2) it's also what 
text-scale-adjust does, (3) it's much faster, (4) if you do not inhibit 
frame resizing the frame can easily become larger than your screen.  Note 
that global-text-scale-adjust uses smaller steps than text-scale-adjust, 
so the user can more easily control the potential undesirable effects.
