switch (access) {
case SkSurface::kFlushRead_BackendHandleAccess:
break;
case SkSurface::kFlushWrite_BackendHandleAccess:
case SkSurface::kDiscardWrite_BackendHandleAccess:
// for now we don't special-case on Discard, but we may in the future.
surface->notifyContentWillChange(SkSurface::kRetain_ContentChangeMode);
// legacy: need to dirty the bitmap's genID in our device (curse it)
surface->getDevice()->accessBitmap(false).notifyPixelsChanged();
break;
