sdlSetRenderDrawColor function
Set the color used for drawing operations (Rect, Line and Clear).
Set the color for drawing or filling rectangles, lines, and points, and for SDL_RenderClear().
\param renderer the rendering context
\param r the red value used to draw on the rendering target
\param g the green value used to draw on the rendering target
\param b the blue value used to draw on the rendering target
\param a the alpha value used to draw on the rendering target; usually
SDL_ALPHA_OPAQUE
(255). Use SDL_SetRenderDrawBlendMode to
specify how the alpha channel is used
\returns 0 on success or a negative error code on failure; call
SDL_GetError() for more information.
\since This function is available since SDL 2.0.0.
