Function axiolid_v0_4_hidden_lines 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn axiolid_v0_4_hidden_lines(
    context: AxiolidContextHandle,
    meshes: *const AxiolidViewMesh,
    mesh_count: usize,
    view: *const AxiolidView,
    edges: *const AxiolidEdgeSelection,
    region: *const AxiolidImageBox,

    out_result: *mut AxiolidResultHandle,
) -> AxiolidStatus

Draw the edges of borrowed meshes with hidden-line removal and return an owned result handle (read it with the hidden_lines_* functions).

meshes and every groups array are borrowed for this call. A null region is no crop. The context’s max_meshes bounds mesh_count.

Safety

Every non-null pointer must be aligned and valid for the documented read or write extent.
