issues with array initialization with functions ([object::default()]),
initializing arrays from a function (implemented a simple gpu version
using manual MaybeUninit pointers),
changing enums with distinct types to structs or changing the selection
logic, changing pointer subtraction in light samplers to a scan (this
will come back to bite me in the ass), and ignoring the data module,
since SPIR-V cant use pointers in statics.
