Point users towards correct fix for "missing capability" errors

1

While trying to get `texpresso` to compile to SPIR-V I very early on encountered an error about a missing `OpCapability Int8`. After some searching around I eventually found out how...

Emulate Image/Sampler API operations on non-SPIRV platforms

1

While the GPU provides hardware for texture sampling and interpolation, on other targets (i.e. CPU in general) it's necessary to emulate that. Currently, the `Image` and `Sampler` APIs don't provide...

Array init with 0i32 uses 0u32 instead.

1

Initializing arrays seems to replace 0i32 with 0u32 when using [0i32; N]. Example (see https://github.com/charles-r-earp/rust-gpu/tree/array-init for compiletests). ``` ; SPIR-V ; Version: 1.3 ; Generator: Google rspirv; 0 ; Bound:...

I'm barely getting started but since the [documentation](https://embarkstudios.github.io/rust-gpu/book/writing-shader-crates.html#writing-shader-crates) recommends to file issues, here is one. ### Example & Steps To Reproduce - `cargo run --bin wgpu_runner` (I guess it should...

Allow keeping linkage annotation

2

SpirV allows defining `import` and `export` [[0](https://registry.khronos.org/SPIR-V/specs/unified1/SPIRV.html#Linkage_Type)] for linking separate Shader modules [[1](https://registry.khronos.org/SPIR-V/specs/unified1/SPIRV.html#_linkage)] post compilation. Apparently SpirV linking is already used within rust-gpu, but not exposed. Therefore we can't use...
