Note: MeshGfx::set_picking_mode() also accepts MESH_EDGES, but I did not manage to read something other than -1.
I though edges were the facet edges (aka the wireframe), and the mesh I tested did not have edges. That is why I got -1 everywhere.
By allowing MESH_EDGES for MeshGfx::set_picking_mode() (the 9 loc of the commit) and by loading a mesh with edges (like CAD feature edges), we can pick edge indices with the demo executable.
PR #102 follow-up, where I wrote:

show_mesh_and have the same colormesh_color_and the same widthmesh_width_, making difficult to distinguish them:
