libgraphene-1.0-dev 1.8.4-1 (s390x binary) in ubuntu disco

 Graphene provides a small set of mathematical types needed to implement
 graphic libraries that deal with 2D and 3D transformations and projections.
 .
 This library provides types and their relative API; it does not deal with
 windowing system surfaces, drawing, scene graphs, or input.
 .
 This package contains the header files required for developing software that
 uses libgraphene.
