Crash in RetainPtr<CGImage*>::RetainPtr via ImageBufferCGBackend::toCFData https://bugs.webkit.org/show_bug.cgi?id=221376 Patch by Frederic Wang <fwang@igalia.com> on 2021-02-15 Reviewed by Said Abou-Hallawa. Source/WebCore: Call to copyNativeImage(CopyBackingStore) may return a null pointer if CGBitmapContextCreateImage does. This patch fixes a crash due to null pointer dereference and adds a similar check for copyNativeImage(DontCopyBackingStore).
