The op-* crate reorg never ran `cargo clippy -- -D warnings`, so the CI lint gate failed. Fix every violation surgically: real fixes for mechanical lints (needless_range_loop, derivable_impls, ptr_arg, needless_borrow, doc_lazy_continuation, unused_imports, manual_find, collapsible_match, never_loop, dead_code, complex types via type aliases) and scoped `#[allow]` for intrusive ones (too_many_arguments on paint helpers, result_large_err where ToolOutcome / PenNode payloads are deliberately the Err type).

//! Spec v19 §9.2 / acceptance #3 / plan v7 Task 2 Step 16f.
|
||
//!
|
||
//! Per-OS dispatch:
|
||
//! - Linux : EGL pbuffer + `SharedSkiaContext` GL surface (non-ignored).
|
||
//! - macOS : invisible winit window + `SharedSkiaContext::new_desktop`
|
||
//! (non-ignored — runs on developer machine + macOS CI).
|
||
//! - Windows: `#[ignore]` per spec §8.1 (no GPU on standard Actions runner;
|
||
//! covered by manual smoke notes).
|
||
//!
|
||
//! All paths drive a single chrome `fill_rect`(red) through the live
|
||
//! pipeline and read pixels back via the FBO chain (spec §7.2 #3).
|
||
//! `gpu_chrome_stub_composition.rs` covers the chrome+stub composition
|
||
//! requested by acceptance #2 over the same GPU surface.
