My previous post ‘XSLT and Binary File Formats‘, brought-up the
subject of the sequence in XSLT 2.0 and how it can be used to
build a byte sequence for a binary file format like a TIFF
image. For the XSLT generation of new binary files to be even
remotely useful, you would need something that requires
transformation into binary data and a way to transform it.  In
the world of 3D computer graphics Pixar are the ‘King of the
hill’ and their Reyes Image Rendering Architecture defines a
very powerful image processing pipeline that is used for the
transformation of complex graphics primitives into smaller,
simpler primitives that are easier to sample and rasterize. The
keyword in the last sentence was transformation, and XSLT is
very good at transforming hierarchical data structures like
computer graphics models.  To simplify the implementation of a
Reyes pipeline processor in XSLT, it makes scene to start with
just two dimensions and use SVG as the source model, while the
final output format can be TIFF (see prev
