-the window in points. For high DPI displays, this will set up scaling from points to

-```c
-    SDL_SetRenderLogicalPresentation(renderer, 0, 0, SDL_LOGICAL_PRESENTATION_DISABLED, SDL_SCALEMODE_NEAREST);

 Mouse and touch events are no longer filtered to change their coordinates, instead you

 the rendering viewport.
