More food for thought: The TeXbook on p.60 says:
-----------------------
\ddanger Magnification is actually governed by \TeX's ^|\mag| primitive,
which is an integer parameter that should be positive and at~most~32768.
The value of\/ |\mag| is examined in three cases: (1)~just before the
first page is shipped to the |dvi| file; (2)~when computing a |true|
dimension; (3)~when the |dvi| file is being closed. Alternatively,
some implementations of \TeX\ produce non-|dvi| output; they examine
|\mag| in case~(2) and also when shipping out each page. Since each
document has only one magnification, the value of\/ |\mag| must not change
after it has first been examined.
