- new `Statement::ImageStore`
- all function calls are `Statement::Call`
- `GlobalUse` is moved out into processing
- `Header` is removed
- entry points are an array instead of a map
- new `Swizzle` and `Splat` expressions
- interpolation qualifiers are extended and required
- struct member layout is based on the byte offsets
