`PolychromeSprite` in `crates/gpui/src/scene.rs` is `#[repr(C)]` and had a `grayscale: bool` field followed by 3 compiler-inserted padding bytes that were never written. The wgpu renderer's `instance_bytes` reinterprets `&[PolychromeSprite]` as `&[u8]` via `slice::from_raw_parts` and passes it to `queue.write_buffer`, so those uninitialized padding bytes were exposed behind a shared `&[u8]` on every frame that draws an image or emoji, which is undefined behavior. Rather than widening the field to a raw `u32` (which would suggest values other than 0 and 1 are meaningful), this introduces `PaddedBool32`: a `#[repr(transparent)]` wrapper around `u32` whose only public constructor is `From<bool>`, so the 0-or-1 invariant is enforced by the type while the layout has no padding. `Underline.wavy`, which was already a raw `u32` for the same reason, is converted too. cbindgen emits the wrapper as `typedef uint32_t PaddedBool32;`, so the generated Metal header and shaders are unchanged. The WGSL and HLSL shaders already declared these fields as `u32`/`uint`; their `& 0xFFu` masks, which existed to ignore the garbage padding bytes, are now simplified to plain comparisons.
