Describes how a client will access the contents of a buffer.

const uint32_t & none ()

If the client sets this field, the client should not set any other

fields in the same table instance. The only valid bit in this field is

`NONE_USAGE` which must be set if this field is set. The point of this

field and the one bit set in this field is to essentially prove that the

client really means they aren't going to use the buffers, so don't need

any VMOs (didn't just fail to fill out the table).
