Florin Malita 46a331b93f [skottie] Cascading track matte support
Currently, we treat track matte source layers (tagged with td:1) as single-shot mask triggers:
we apply once to the following layer, then move on.

But track mattes can cascade: a layer with a matte can itself be applied as a track matte for the
following layer.

Also, for matte/masking purposes, only the layer content is being considered (ignoring blend mode
and any masks applied to the matte itself).

To support this, refactor the layer attachment code:

  - instead of tracking the presence of a single-shot matte source, always track
    previous layer content trees
  - instead of triggering matte attachment in the presence of a matte source, trigger based on
    the matte *target* property (tt: X)
  - log errors on unknown matte modes
