Get logical coordinates of point in renderer when given real coordinates of point in window.

```
void SDL_RenderWindowToLogical(SDL_Renderer * renderer,
int windowX, int windowY,
float *logicalX, float *logicalY);
```

renderer |
the renderer from which the logical coordinates should be calculated |

windowX |
the real X coordinate in the window |

windowY |
the real Y coordinate in the window |

logicalX |
the pointer filled with the logical x coordinate |

logicalY |
the pointer filled with the logical y coordinate |

Logical coordinates will differ from real coordinates when render is scaled and logical renderer size set

This function is available since SDL 2.0.18.
