mrv2 v1.2.9

[ggarra13]

v1.2.9

• Handle AV_DISPOSITION_ATTACHED_PIC properly, instead of skipping it.
• Added PNG decoder so attached png pictures in .wav files are decoded properly.
• Added a File->Save Annotations Only. This allows you to export the annotations as a movie or file sequence.
• Added a File->Save Annotations as JSON. This allows you to export the annotations as a .json file.
• Fixed a crashing bug when drawing freehand.
• Fixed disappearing cursor when selecting a drawing tool.
• Added polygon drawing to the drawing tools.
• Polygon, Circle and Rectangle have two modes (outline or filled now). You select the mode by clicking on each triangle edge of the button.
• Fixed Float on Top on start up on Linux X11.
• Added pip.sh for Unix systems to easily install pip libraries inside mrv2's
  python library directory.
• Moved mrv2's ComfyUI directory to its own repository at:
  https://github.com/ggarra13/ComfyUI-mrv2
  so that it can be listed more easily in ComfyUI's Node Manager AND we
  make it more clear that that project is GPL compatible, not BSD one.
• Fixed selecting montior's Display/View to None from the Menus.
• Updated OpenColorIO to v2.3.4.
