[Carto] Map specifications

[Miller, Craig]

I would think that any work on this should be done as an addition to an
existing layout manager.  I believe it was the Inkscape forums where I saw a
thread discussing the possible extension of an existing layout manager for
their application.  Perhaps this group can do the same?  I would think a
good first start would be to put together a summary of existing free/open
source layout managers.

Also, from a large plot perspective something like RTL needs to be supported
as a plotting language.  This allows really really big plots to be streamed
to a printer/plotter rather than requiring the entire file to fit into the
printer/plotters memory (a la postscript).  With a streaming format the
plotter can print/plot as it is received.
