-/* If DPI is close enough to some magstep of BDPI, return the true dpi
- value, and the magstep found (or zero) in M_RET (if
- non-null). ``Close enough'' means within one pixel.
-
- M_RET is slightly encoded: the least significant bit is on for a
- half-magstep, off otherwise. Thus, a returned M_RET of 1 means
- \magstephalf, i.e., sqrt(1.2), i.e., 1.09544. Put another way,
- return twice the number of magsteps.
-
- In practice, this matters for magstephalf. Floating-point computation
- with the fixed-point DVI representation leads to 328 (for BDPI ==
- 300); specifying `at 11pt' yields 330; the true \magstephalf is 329
- (that's what you get if you run Metafont with mag:=magstep(.5)).
-
- The time to call this is after you read the font spec from the DVI
- file, but before you look up any files -- do the usual floating-point
- computations, and then fix up the result. */
