I don't understand why there's a non-transactional version of this? It should just dirty the transaction and be sent that way (so that it, again, is synchronized with the layer content in the transaction).

This is only called inside `TiledCoreAnimationDrawingArea::updateRendering`.  This is also how `themeColor` and `pageExtendedBackgroundColor` do it.  It was my understanding that this is how it's done for macOS?  Am I mistaken?
