The DVI2BITMAP_PK_PATH environment variable now accepts a
colon-separated list of directories to search. The font searching
algorithm which uses that variable now does the font-size rounding
calculation properly, and will additionally search for fonts within
0.2% of the target size, as required by the DVI Driver
Standard.
The kpathsea font searching mechanism is still the preferred way of finding fonts, but since many folk don't have, or don't want to obtain, access to the library, I've made the simple font-searching algorithm marginally more sophisticated, as described above.
