Multiple bugs here: 1) Like texture(), GLSL's textureLod() on depth textures returns a scalar, and does not need to be swizzled. So set glsl_ret_width to 1 in that case. 2) Like texture(), GLSL's textureLod() always requires a Dref parameter, so append a zero if not present. 3) GLSL's "lod" parameter to textureLod() is always a float, unlike WGSL's textureSampleLevel() which is an i32 for depth textures, so cast it. Along the way, I discovered that textureLod() is not supported on samplerCubeShadow or sampler2DArrayShadow (even on Desktop GL). So some tests will never pass.
