'''
The RmanScene handles translating the Blender scene.
Attributes:
rman_render (RmanRender) - pointer back to the current RmanRender object
rman () - rman python module
sg_scene (RixSGSCene) - the RenderMan scene graph object
context (bpy.types.Context) - the current Blender context object
depsgraph (bpy.types.Depsgraph) - the Blender dependency graph
bl_scene (bpy.types.Scene) - the current Blender scene object
bl_frame_current (int) - the current Blender frame
bl_view_layer (bpy.types.ViewLayer) - the current Blender view layer
rm_rl (RendermanRenderLayerSettings) - the current rman layer
do_motion_blur (bool) - user requested for motion blur
rman_bake (bool) - user requested a bake render
is_interactive (bool) - whether we are in interactive mode
external_render (bool) - whether we are exporting for external (RIB) renders
is_viewport_render (bool) - whether we are rendering into Blender's viewport
scene_solo_light (bool) - user has solo'd a light (all other lights are muted)
rman_materials (dict) - dictionary of scene's materials
rman_translators (dict) - dictionary of all RmanTranslator(s)
rman_particles (dict) - dictionary of all particle systems used
rman_cameras (dict) - dictionary of all cameras in the scene
obj_hash (dict) - dictionary of hashes to objects ( for object picking )
moving_objects (dict) - dictionary of objects that are moving/deforming in the scene
motion_steps (set) - the full set of motion steps for the scene, including
overrides from individual objects
main_camera (RmanSgCamera) - pointer to the main scene camera
rman_root_sg_node (RixSGGroup) - the main root RixSceneGraph node
render_default_light (bool) - whether to add a "headlight" light when there are no lights in the scene
world_df_node (RixSGShader) - a display filter shader that represents the world color
default_light (RixSGAnalyticLight) - the default "headlight" light
viewport_render_res_mult (float) - the current render resolution multiplier (for IPR)
num_object_instances (int) - the current number of object instances. This is used during IPR to
track the number of instances between edits. We try to use this to determine
when an object is added or deleted.
num_objects_in_viewlayer (int) - the current number of objects in the current view layer. We're using this
to keep track if an object was removed from a collection
objects_in_viewlayer (list) - the list of objects (bpy.types.Object) in this view layer.
