| Backend specific texture infos, e.g. `DawnTextureInfo`, | |
| `VulkanTextureInfo`, and `MtlTextureInfo`'s `fSampleCount` field, and the | |
| `ContextOptions::fInternalMultisampleCount` field are now `SampleCount`. A helper | |
| function, `ToSampleCount(uint32_t) -> SampleCount` is provided if needing to convert a variable value vs. just updating a constant. |
