GfxState: SurfaceStore (slot->{resId,colorkey} from create/set-texture) + object
SourceSlot/SrcRect/Visible (from draw-texture bind); SnapshotVisibleObjects returns
visible objects in ascending-handle order (=z-order) with their live surface resolved.
VM set/create/draw-texture wired to it. Oracle dumps visible objects. Erase removes the
object from the registry (faithful). Engine 44 green.
