In our other SpecialFlower model, force island models to be loaded, baked, and available by specifying them as a dependency in IModel.

Item model will be some ISmartItemModel that looks at the type of flower and island and automatically returns a MultiModel.Baked with the correct components.

MultiModel.Baked takes a base model and aux models.
The base model can be perspective aware and is transformed as such.
Thus, we want the base model to be a perspective aware wrapper around the flower model that always translates its parent model down.
The aux model will be the island.

The tile entity renderer will simply remember the itemstack used to make it and render it big and make it sparkle and rotate.
