Have you tried to add these dependencies to gain potentially more
rendering input/output:

libwebp
cairo
sqlite

Many files under ./demo are licensed under "license:gpl2.0+". Add that
license, too.

Furthermore, there are:

license:boost1.0 ;; deps/boost
license:bsd3 ;; deps/mapbox and deps/mapnik/sparsehash

Finally, dep/agg has another license. Is it expat or even less? Here it
is:

// Permission to copy, use, modify, sell and distribute this software
// is granted provided this copyright notice appears in all copies.
// This software is provided "as is" without express or implied
// warranty, and with no claim as to its suitability for any purpose.



Otherwise, LGTM.
