sdlRenderCoordinatesToWindow function render
Get a point in window coordinates when given a point in render coordinates.
This takes into account several states:
- The window dimensions.
- The logical presentation settings (SDL_SetRenderLogicalPresentation)
- The scale (SDL_SetRenderScale)
- The viewport (SDL_SetRenderViewport)
\param renderer the rendering context. \param x the x coordinate in render coordinates. \param y the y coordinate in render coordinates. \param window_x a pointer filled with the x coordinate in window coordinates. \param window_y a pointer filled with the y coordinate in window coordinates. \returns true on success or false on failure; call SDL_GetError() for more information.
\threadsafety This function should only be called on the main thread.
\since This function is available since SDL 3.2.0.
