[Dvipng] dvipng 1.10

[Jan-Åke Larsson]

elease notes for version 1.10 of the dvipng package:

This program makes PNG graphics from DVI files as obtained from TeX
and its relatives.


From v 1.10, dvipng will be available under the LGPL rather than the
GPL. This is because the GPL restricts inclusion in some rendering
systems out there. I have decided to change to LGPL because a) there
are other possible albeit slower conversion paths from DVI to PNG, and
b) dvipng has been available (pre-release and release) for five years
now, which should be enough of a head start for the GNU community.


The main code addition is limited support for literal PostScript
specials, using gs. For example, most of the PSTricks package can now
be rendered using dvipng. Unfortunately, dvipng can only handle
drawing PostScript code at the moment, not PostScript code intended to
make dvips + gs scale, rotate, or move DVI glyphs (characters).  This
is because the graphics state cannot be communicated back to dvipng
from gs. So no guarantees. Also, the performance in terms of runtime
could be better.

Other changes include internal changes to the DVI stack, DVI flags,
some build issues on AIX and glyph-index-checking fixes.
