              Variables are the core of the scene producer realtime animation possibilities.
              In this section the user defined variables are specified.
              Public variables are accessible as CG parameters and by the parent scene when nested inside another.
              There are some variables that are always defined like
              "frame" which stores the number of frames that have gone by since the scene producer started,
              "mouse_x" and "mouse_y" which reflect the X and Y position of the mouse at all times relative to the scene coordinate system (requires interaction aware consumer like screen_consumer),
              "timeline_frame" which differs from "frame" in that it can rewind and jump, depending on where the timeline is at the moment,
              "fps" which always contains the framerate of the scene and
              "scene_width" and "scene_height" which contains the dimensions of the scene coordinate system.

              Marks are placed on specific timeline frames and marks start of animation sequences, stop of animation sequence and removal of the entire scene.
              They affect what happens when CG PLAY, CG STOP, CG INVOKE and CG NEXT are sent via AMCP.

                  <xs:documentation>
                    One of the mark types is "start" which marks the start of a named animation. There is an implicit start mark at frame 0 called "intro" which is started when CG PLAY is executed. The "intro" animation can be defined at another frame if desired. There is another start mark that should be called "outro" which is coupled to CG STOP. Any other start mark is used with CG INVOKE.
                    Another mark type is "stop" which makes the timeline stop when reached. The only thing that can make the timeline move again is a CG NEXT, CG STOP or a CG INVOKE.
                    The "jump_to" mark type tells the timeline to jump to another "start" whenever reached, enabling the possibility of creating animation loops.
                    The last mark type is "remove" with the only purpose of completely stopping rendering when reached. It is used instead of "stop" to mark the end of the "outro" animation.
                    Note that a "stop" or "jump_to" can be on the same frame as a "start" for example on end of intro and start of outro. There will be no conflict in this case when outro is started.

                        "jump_to" means that the entire timeline should jump to the mentioned start label whenever the frame is encountered.
                        "remove" is usually the end of the "outro" animation and causes the scene to stop rendering completely.
