Summary

Works almost exclusively on the GTK and WPE ports' graphics stack — CoordinatedGraphics, the Skia compositor, and the platform layer plumbing under WebCore. Nothing here is security-labeled; the recent cluster is concurrency correctness instead — turning on `-Wthread-safety` for both ports and then fixing what it flagged, narrowing lock scope in `CoordinatedPlatformLayer`, moving `CoordinatedAnimatedBackingStoreClient` ownership to the backing store, and stopping early release of hole-punch buffers on layer invalidation. Systematic-variant candidate: cross-thread ownership and buffer-release paths in the coordinated compositor, where a compositor-thread lifetime bug and multiple regression fixes have recently landed in the same files.
