A variable controlling whether the OpenGL render driver uses shaders if they are available.
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_OPENGL_SHADERS "SDL_RENDER_OPENGL_SHADERS"
This variable can be set to the following values: "0" - Disable shaders "1"
By default shaders are used if OpenGL supports them.
