An experimental module for reading dvi files output by TeX. Several
limitations make this not (currently) useful as a general-purpose dvi
preprocessor, but it is currently used by the pdf backend for
processing usetex text.
Interface::
dvi = Dvi(filename, 72)
# iterate over pages (but only one page is supported for now):
for page in dvi:
w, h, d = page.width, page.height, page.descent
for x,y,font,glyph,width in page.text:
fontname = font.texname
pointsize = font.size
...
for x,y,height,width in page.boxes:

A dvi ("device-independent") file, as produced by TeX.
The current implementation only reads the first page and does not
even attempt to verify the postamble.

Initialize the object. This takes the filename as input and
opens the file; actually reading the file happens when
iterating through the pages of the file.

Iterate through the pages of the file.
Returns (text, boxes) pairs, where:
text is a list of (x, y, fontnum, glyphnum, width) tuples
boxes is a list of (x, y, height, width) tuples
The coordinates are transformed into a standard Cartesian
coordinate system at the dpi value given when initializing.
The coordinates are floating point numbers, but otherwise
precision is not lost and coordinate values are not clipped to
integers.

For historical reasons, TeX knows many Type-1 fonts by different
names than the outside world. (For one thing, the names have to
fit in eight characters.) Also, TeX's native fonts are not Type-1
but Metafont, which is nontrivial to convert to PostScript except
as a bitmap. While high-quality conversions to Type-1 format exist
and are shipped with modern TeX distributions, we need to know
which Type-1 fonts are the counterparts of which native fonts. For
these reasons a mapping is needed from internal font names to font
file names.
A texmf tree typically includes mapping files called e.g.
psfonts.map, pdftex.map, dvipdfm.map. psfonts.map is used by
dvips, pdftex.map by pdfTeX, and dvipdfm.map by dvipdfm.
psfonts.map might avoid embedding the 35 PostScript fonts (i.e.,
have no filename for them, as in the Times-Bold example above),
while the pdf-related files perhaps only avoid the "Base 14" pdf
fonts. But the user may have configured these files differently.

The format is, AFAIK: texname fontname [effects and filenames]
Effects are PostScript snippets like ".177 SlantFont",
filenames begin with one or two less-than signs. A filename
ending in enc is an encoding file, other filenames are font
files. This can be overridden with a left bracket: <[foobar
indicates an encoding file named foobar.
