[Bf-committers] Multi Layer EXR issues

[François T.]

maybe its a good time to introduce a shuffle kind of node, which would let
you select any pass in a multi-layer and/or channels ? that would replace a
long list of passes in the reader node and also help on some small
operation with channels.

cheers,

F.
