// Parameters:
// - |usage|: Indicates the category of GPU memory usage being tracked.

// with the work done here on the UI thread.
// - |peak_memory|: The total peak GPU memory usage in bytes.
// - |allocation_per_source|: A breakdown of the peak memory usage, showing how
// much was allocated by each source.
