The GLSL to MSL conversion process uses a passed-in sampler state for the `iChannel0` parameter and we weren't providing it. This magically worked on Apple Silicon for unknown reasons but failed on Intel GPUs. In normal, hand-written MSL, we'd explicitly create the sampler state as a normal variable (we do this in `shaders.metal` already!), but the Shadertoy conversion stuff doesn't do this, probably because the exact sampler parameters can't be safely known. This fixes a Metal validation error when using custom shaders: ``` -[MTLDebugRenderCommandEncoder validateCommonDrawErrors:]:5970: failed assertion `Draw Errors Validation Fragment Function(main0): missing Sampler binding at index 0 for iChannel0Smplr[0]. ```
