SPIR-V backend:
- fix auto-deriving the capabilities
GLSL backend:
- support sample interpolation
- write out swizzled vector accesses

v0.4.1 (2021-05-14)

numerous additions and improvements to SPIR-V frontend:
- int8, in16, int64
- null constant initializers for structs and matrices
- OpArrayLength, OpCopyMemory, OpInBoundsAccessChain, OpLogicalXxxEqual
- outer product
- fix struct size alignment
- initialize built-ins with default values
- fix read-only decorations on struct members
fix struct size alignment in WGSL
fix fwidth in WGSL
fix scalars arrays in GLSL backend

v0.4 (2021-04-29)

development release for wgpu-0.8
API:
- expressions are explicitly emitted with Statement::Emit
- entry points have inputs in arguments and outputs in the result type
- input/output storage classes are gone, but push_constant is added
- Interpolation is moved into Binding::Location variant
- real pointer semantics with required Expression::Load
- TypeInner::ValuePointer is added
- image query expressions are added
- 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
Infrastructure:
- control flow uniformity analysis
- texture-sampler combination gathering
- CallGraph processor is moved out into glsl backend
- Interface is removed, instead the analysis produces ModuleInfo with all the derived info
- validation of statement tree, expressions, and constants
- code linting is more strict for matches
new GraphViz dot backend for pretty visualization of the IR
Metal support for inlined samplers
convert example is transformed into the default binary target named naga
lots of frontend and backend fixes
