This may not be what you're looking for (I haven't been
following your discussion).  However, in hopes that it
will be useful, I recommend the following sources of
information on rasterization:

The documentation for the PNG (Portable Network Graphics)
format:
http://www.libpng.org/pub/png/index.html

The documentation for the GNU Plotutils package:
http://www.gnu.org/software/plotutils/plotutils.html

The following book may also contain useful information:

Miano, John.
{\it Compressed Image File Formats}.
Addison Wesley Longman, Inc.
Reading, Massachusetts 1999.
ISBN 0-201-60443-4

David Salomon's book, which has come up on this list
before, also discusses rasterization:

Salomon, David.
@i{Computer Graphics and Geometric Modeling}.
Berlin 1999.
Springer-Verlag.
