Resolves issue with nearest filtering on UI Icons. Note that as Metal does not support LOD bias as a parameter on a sampler object, the original code has been modified to perform LOD biasing at the shader level. As GPU_SAMPLER_ICON is not widely used, it is more efficient to apply directly to the affected shaders, rather than workaround passing in the sampler LOD bias as a separate value e.g. uniform or push constant. Original PR feedback addressed to also refactor ICON shaders to use consistent style for single and multi Icon rendering. Authored by Apple: Michael Parkin-White Ref #96261 Pull Request #105145
