sdlGetRenderDrawColorFloat function render
Get the color used for drawing operations (Rect, Line and Clear).
\param renderer the rendering context. \param r a pointer filled in with the red value used to draw on the rendering target. \param g a pointer filled in with the green value used to draw on the rendering target. \param b a pointer filled in with the blue value used to draw on the rendering target. \param a a pointer filled in with the alpha value used to draw on the rendering target. \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.
