| Graphite's `Context` now provides an interface to report the GPU time spent processing a recording. The client provides |
| a different finished proc of type `skgpu::graphite::GpuFinishedWithStatsProc` using |
| `skgpu::graphite::InsertRecordingInfo::fFinishedWithStatsProc` and sets the flag |
| `skgpu::graphite::InsertRecordingInfo::fGpuStatsFlag` to `skgpu::GpuStatsFlags::kElapsedTime`. The new callback takes a |
| new struct, `skgpu::GpuStats`, which has an `elapsedTime` field that will indicate the amount of GPU time used by the |
| recording. This is implemented for the Dawn backend only. In WASM on WebGPU the reported time excludes any GPU transfers |
| that occur before the first render/compute pass or after the last pass because of limitations in the WebGPU timestamp |
| query API. |
| |
| `GrDirectContext` provides a similar interface to report the GPU time spent in a flush. The client uses a new callback |
| type, `GrGpuFinishedWithStatsProc` and sets the same flag on `GrFlushInfo`. This is implemented for GL |
| (including GLES and WebGL). |
