It's four pointers, twice as much as what would be acceptable. Not sure
why this happened, maybe because all those cases used an ArrayView
before and so I just changed the type without considering the difference
in its size?
Unfortunately this change also means a bump in the plugin interface
string, thus all scene converter plugins have to be updated as well.
Same as the previous commit in MeshTools -- allows to pass a
Containers::Array<DescriptorSetLayoutBinding> to it without having to
form a list of references first.
Together with DescriptorBindingFlags, because it affects the design in a
rather specific way and it wouldn't make sense to postpone this and
forget all again until it becomes needed.
