gir1.2-graphene-1.0 1.10.8-1 (riscv64 binary) in ubuntu mantic

 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 can be used by other packages using the GIRepository format to
 generate dynamic bindings.
