A variable controlling the scaling quality
Defined in [SDL_hints.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_hints.h), but apps should _only_ `#include "SDL.h"`!
#define SDL_HINT_RENDER_SCALE_QUALITY "SDL_RENDER_SCALE_QUALITY"
This variable can be set to the following values: "0" or "nearest" - Nearest pixel sampling "1" or "linear" - Linear filtering (supported by OpenGL and Direct3D) "2" or "best" - Currently this is the same as "linear"
By default nearest pixel sampling is used
By default nearest pixel sampling is used.
