+Write-only Textures
+---------------
+
+Many image formats supported by WebGPU can only be accessed in compute shader as a write-only image.
+Use `WTexture2D` type (similar to `RWTexture2D`) to write to an image when possible.
+The write-only texture types are also supported when targeting HLSL/GLSL/SPIR-V/Metal and CUDA.
