Default capacity of buffers on new collections. A quantity of elements: number of vertices in the vertex buffer, primitives in the primitive buffer, etc. This value is arbitrary, and collections cannot be resized, so specific per-buffer capacities should be provided in the collection constructor when available.

Duplicates the contents of this collection into the result collection. Result collection is not resized, and must contain enough space for all primitives in the source collection. Existing primitives in the result collection will be overwritten.
