Where does a new gallery design belong — the core Gallery or the 3D Gallery?
The question: a "Photo Scatter" effect — photos scattered flat on a tabletop, gliding in from
the edges, dwelling, then reshuffling to the next set — is unmistakably a gallery. The core
[gallery] element already has 20+ layout designs. So does a new gallery design belong there, or
in the Animation Engine's [gallery_3d]?
