Frame Animation Sequence

Source: https://github.com/yttiktak/inkscape_extension_animate

Create svg path animation from frames: Place each frame of the animation in a layer named 'frame'. Each of these layers should have the same number of paths, and each path should have the same number of points as the corresponding path in other layers. The animation is applied to the paths in the first layer in the sequence, so the properties of that layer are used. Animations with different numbers of frames can be put into different sequences, named 'sequence', using sub-groups:

Layers structure example

 not_animated_layer1
 sequence
  frame
   path1a
   path2a
  frame
   path1b
   path2b
  frame
   path1c
   path2c
  frame
   path1d
   path2d
 sequence
  frame
  frame
  frame 

Use layer named exactly 'frame' and groups named exactly 'sequence', not, eg, frame1 frame2 frame3 !
