Vector Shapes Strip for Sequencer

I propose a special strip for the sequencer that:

• allows the creation of vector shapes directly in the sequencer
• the vector shapes are bound to the strip and can be moved around the timeline
• the vector shapes should be animatable
• it is basically a strip version of the mask editor (in the video clip editor)
• shows a strip-specific toolbar if selected in video preview windows. The toolbar could contain:
  • Vector Path manipulation tools
  • premade shapes like Circle, Square, Star ... the usual
• Use those vector shape strips directly as masks
• Use the strips as any kind of decorative elements (Color them via masking a color strip)

It would make working with masks a bit more like in Premiere and in general a lot easier and faster.
