A given entry corresponds to a buffer, but a single buffer may contain attributes of multiple different interlaced attributes, hence the attribute permutation parameter which lists the various attributes that can be found in the buffer, and in which order.

A given entry corresponds to a buffer, but a single buffer may contain attributes of multiple different interlaced attributes, hence the attribute permutation parameter which lists the various attributes that can be found in the buffer, and in which order. If stride doesn't exactly match the format, the GPU may hang.
When the entry is unused, the entry data is all-zero.
