 *      so we first have to add a way to query those... no Ender, I don't
 *      think a bitmasked property() value is nice for this,  because we would
 *      have to add to the bitmask values whenever a backends adds a new scaler).
 *   2) At the time the launcher is running, the GFX backend is already setup.
 *      So when a game is run via the launcher, the custom scaler setting for it won't be
 *      used. So we'd also have to add an API to change the scaler during runtime
 *      (the SDL backend can already do that based on user input, but there is no API
 *      to achieve it)
 *   If the APIs for 1&2 are in place, we can think about adding this to the Edit&Option dialogs
