Summary: We often want to iterate over frames in the sequence in temporal order. This diff provides the API to do that. `seq_to_idx` should probably be considered to have `protected` visibility.

Summary:
Fixes required for MC rasterisation to work.
1) Wrong number of channels for background was used (derived from points dimensions, not features dimensions;
2) split of the results on the wrong dimension was done;
3) CORE CHANGE: blending in alpha compositor was assuming RGBA input.

Summary: As reported in https://github.com/facebookresearch/pytorch3d/pull/1100, a rasterizer couldn't be moved if it was missing the optional cameras member. Fix that. This matters because the renderer.to calls rasterizer.to, so this to() could be called even by a user who never sets a cameras member.
