Removed unused Main* argument to the USDStageReader constructor.

Fix new shadow catcher not handling emissive meshes correctly

These must also be excluded from direct light sampling for the shadow
catcher pass.

LineArt: Use enum for stroke_depth_order.

This is for gpencil object adding.

Merge remote-tracking branch 'origin/master' into temp-lineart-contained

LineArt; intersection flag variables.

USD IO: updated addons_contrib submodule.

The export_textures and relative_texture_paths options are now
enabled by default.

Cycles X: Initial implementation of shadow catcher

It is re-implemented in a way which does differential rendering: the
path is split at a first non-transparent bounce when shadow catcher
object is hit. One path will track state of the shadow catcher object
without other objects affecting it. The other path is rendering scene
as usual.

Upon user access of the shadow catcher pass the result is calculated
as combined pass divided by the pass with shadow catcher object. This
gives a pass which is to be multiplied with a backdrop to transport
light and shadows caught.

For the artificial objects which are to be added to the backdrop
there is an internal matte pass. This pass is presented as combined
to artists, so they alpha-over it onto the footage as usual. In the
future we might implement shadow approximation to gain old-style
shadow catcher behavior (maybe for compatibility reasons, maybe for
some artistic reasons).

This process is a bit more involved that the old single pass approach,
but it allows to deal with indirect light, caustics.
