SDL_HINT_VIDEO_WAYLAND_MODE_SCALING - A variable controlling how modes with a non-native aspect ratio are

       This hint is available since SDL 3.2.0.

Simple Directmedia Layer                           SDL 3.2.10             SDL_HINT_VIDEO_WAYLAND_MODE_SCALING(3)

       When  this  hint  is  set, the requested scaling will be used when displaying fullscreen video modes that
       don't match the display's native aspect ratio.  This is contingent on compositor viewport support.

       The variable can be set to the following values:

       • "aspect" - Video modes will be displayed scaled, in their proper aspect
         ratio, with black bars.

       • "stretch" - Video modes will be scaled to fill the entire display.
         (default)

       • "none" - Video modes will be displayed as 1:1 with no scaling.

       This hint should be set before creating a window.
