Create svg path animation from frames.
Create svg path animation as SMIL 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.
Note if there are more than one path in the frames, the Z order of the paths
must match. It helps to use the XML editor option to observe the z order.
The animation is applied to the paths in the first layer in the sequence, so the
properties of that layer are used.
properties of that layer are used. In particular, the first layer ought to be set
visible.
Animations with different numbers of frames can be put into different sequences,
named 'sequence', using sub-groups:

Layer names must contain 'frame' and groups names contain 'sequence',

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