Renderer allocation policy requested by a
SceneModel.
This is a hint, not a hard memory limit. It tells renderers whether they
should use their normal reusable storage strategy or allocate tightly around
finalized content.
"stream": default. Use for open, streaming or editable models. Renderers
may keep reusable backing stores that can accept more content without
repacking.
"compact": use for sealed models or committed batches whose contents are
expected to remain immutable. Renderers should allocate close to the
current content size where supported.
