Perform a fast fill of a rectangle with a specific color.
int SDL_FillRect const SDL_Rect * rect, Uint32 color); (SDL_Surface * dst,
|dst||the SDL_Surface structure that is the drawing target|
|rect||the SDL_Rect structure representing the rectangle to fill, or NULL to fill the entire surface|
|color||the color to fill with|
Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
color should be a pixel of the format used by the surface, and can be generated by SDL_MapRGB() or SDL_MapRGBA(). If the color value contains an alpha component then the destination is simply filled with that alpha information, no blending takes place.
If there is a clip rectangle set on the destination (set via SDL_SetClipRect()), then this function will fill based on the intersection of the clip rectangle and
This function is available since SDL 2.0.0.
