If 513 draw instances are batched into blocks of 512, the renderer will dedicate a whole block to the last element and any subsequent calls will allocate a third block and start from an entirely new buffer.

Ideally the existing buffer could be used for data belonging to a separate set of instance draws, and instead the runtime would keep track of what range across the buffers belongs to what draw command.

instance_buffers: [ 512/512, 34/512 ]
command_ranges: [408, 104, 34]
