SDL_HINT_TRACKPAD_IS_TOUCH_ONLY - A variable controlling whether trackpads should be treated as touch

       This hint is available since SDL 3.2.0.

Simple Directmedia Layer                           SDL 3.2.20                 SDL_HINT_TRACKPAD_IS_TOUCH_ONLY(3)

       On macOS (and possibly other platforms in the future), SDL will report touches on  a  trackpad  as  mouse
       input,  which  is  generally  what  users expect from this device; however, these are often actually full
       multitouch-capable touch devices, so it might be preferable to some apps to treat them as such.

       The variable can be set to the following values:

       • "0": Trackpad will send mouse events. (default)

       • "1": Trackpad will send touch events.

       This hint should be set before SDL is initialized.

       devices.
