I changed the dependencies as follows:

   s.add_runtime_dependency 'asciidoctor', '>= 1.5.3', '< 3.0.0'
-  s.add_runtime_dependency 'prawn', '~> 2.2.0'
+  s.add_runtime_dependency 'prawn', '~> 2.3.0'
   # NOTE ttfunk 1.6 generates TT instructions ghostscript cannot process, so lock the version of ttfunk
-  s.add_runtime_dependency 'ttfunk', ['~> 1.5.0'], ['>= 1.5.1']
+  s.add_runtime_dependency 'ttfunk', ['~> 1.5'], ['>= 1.5.1']
   # NOTE must use prawn-table from master branch (defined in Gemfile) for full functionality
   s.add_runtime_dependency 'prawn-table', '~> 0.2.0'
   # s.add_runtime_dependency 'prawn-templates', '~> 0.1.0'

Running the asciidoctor-pdf test suite , I'm getting a bunch of new
regressions, but all of the new errors are just integer-vs-float
changes:

        expected: 12.0
             got: 12

Otherwise, looks good. If this seems reasonable, I'll go ahead and
adjust the debian dependencies to match and get it packaged up.

We still don't have a prawn-templates package, so I'm still disabling
embedded PDF images. Last time I tried to package this, it was still
modifying the 'prawn' code as a part of this package, which seems
inappropriate for a Debian package.

Thanks for your help with this stuff!
