Great!  Glad you like it.  I had no idea either, until i thought to myself,
hmm -- it's open source, how hard can it be?  And then i started digging
around in the Inkscape folder.

Good idea.  I now use a typewriter font for variable names to distinguish
them from object "true names".


Okay, there is now a new version of the figure:

    http://zesty.ca/promises/pipeline3.svg

This version provides a later view with the messages in the second vat's
queue.  The following three images are all generated from this file by
turning various layers on and off:

    http://zesty.ca/promises/pipeline-transit.svg
        (The messages are in transit between the vats.)

    http://zesty.ca/promises/pipeline-queue.svg
        (The messages are queued in the second vat, but the result
        pointer is not shown.)

    http://zesty.ca/promises/pipeline-result.svg
        (The messages are queued in the second vat, and the result
        pointer is shown.)

I'm only showing the second option here because the third is a little
messier.  But the most useful pictures to show are probably the first
and third, if you have the space to show them.

This figure is bigger and smaller at the same time.  By this, i mean
the figure itself has more detail, and if it were shown at the same
scale as the previous version it would be larger.  But it has a wider
aspect ratio, so if you scale it to the text width, it will actually
take up less space in the paper.

All of my previously posted files related to this paper have been
moved into the http://zesty.ca/promises/ directory.
