"""
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:
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 !
