- samplerCubeShadow requires vec3 gradients
- Bias must be written after offset
- sampler1D hack on GLES requires vec2 gradients
- textureSize doesn't accept a lod argument for MS samplers
- sampler1DArray hack on GLES requires a y component on imageLoad
This one grew out of hand quick. Initially it was just replacing the bit
loops with a function driving the declarations to make the code sharing
better and support different scalar kinds.
Now it includes a lot of fixes:
- `textureSize` now also returns the array layers as the last component
on the return (only for arrayed textures)
- `textureSize` now supports multisampled textures
- the `texture` family of functions now consumes a `vec3` coordinate
vector for all 1D shadow textures
- Shadow textures can use the bias version of `texture` functions
(temporarily disabled since naga doesn't support it)
- 3D textures can be used in `textureProj`
- `sampler2DArrayShadow` can't be used in `textureLod` or in `texture` with bias
- Cube textures cannot be used with offsets
Updates the tests to cover all functions
* Allow vecN<i32> and vecN<u32> in `dot()`, first changes
* Added a test case
* Fix the test
* Changes to baking of expressions, incl args of integer dot product
* Implemented requested changes for glsl backend
* Added support for integer dot product on MSL backend
* Removed outdated code for hlsl and wgls writers
* Implement in spv backend
* Commit modified outputs from running the tests
* cargo fmt
* Applied requested changes for both MSL and GLSL back
* Changes to spv back
* Committed all test output changes
* Cargo fmt
* Added a comment w.r.t. VK_KHR_shader_integer_dot_product
* Implemented requested svp change
* Minor change to test case
This is because I wanted to highlight the fact that the correct
id is used in the last sum of the integer dot product expression
* Changed function signature
since it could not fail, changed it to simply return `void`
