//
// The library maintains a registry of named DDS scene graphs. A "default"
// scene always exists and cannot be destroyed.  Immediate-mode draw calls
// (circle, box, wxbgi_world_line, etc.) always append to the *active* scene.
// Each camera renders its *assigned* scene (see wxbgi_cam_set_scene).
//
// Typical usage:
//   wxbgi_dds_scene_create("secondary");         // create a second scene
//   wxbgi_dds_scene_set_active("secondary");     // route draws to it
//   wxbgi_world_box(0,0,0, 5,5,5);              // appends to "secondary"
//   wxbgi_dds_scene_set_active("default");       // switch back
//   wxbgi_cam_set_scene("cam_side", "secondary");// cam_side renders "secondary"
//   wxbgi_render_dds("cam_main");               // renders "default" scene
//   wxbgi_render_dds("cam_side");               // renders "secondary" scene
