[Bf-committers] New Alembic support branch

[Esteban Tovagliari]

I recently updated the exporter to use the new camera sensor sizes and
other recent changes.
I also added frame relative sampling and some more options.

Missing are support for DupliX, particles and curves. Dynamic paint vertex
color export
also does not work yet, not sure why.

The code is at https://github.com/est77/BlenderVFX. The master branch is
a mirror of blender's svn trunk, for reference and the Alembic branch
contains the exporter.

If you want to contribute, you can fork the code and do pull requests or
send me patches
and I'll merge them.
