:mrdocs:

Create a sequential allocator for allocating memory blocks from a sequence of dynamically‐allocated buffers, of which the initial buffer has the specified `initialSize` (in bytes), and the buffer growth is limited to the specified `maxBufferSize`. Optionally specify a `basicAllocator` used to supply memory for the dynamically‐allocated buffers. If `basicAllocator` is 0, the currently installed default allocator is used. Optionally specify a `growthStrategy` used to control buffer growth. If no `growthStrategy` is specified, geometric growth is used. Optionally specify an `alignmentStrategy` used to control alignment of allocated memory blocks. If no `alignmentStrategy` is specified, natural alignment is used. The behavior is undefined unless `0 < initialSize` and `initialSize <= maxBufferSize`. Note that when constant growth is used, the size of the internal buffers will always be the same as `initialSize`.
