* This function is equivalent to the SDL 1.2 API SDL_UpdateRects().
|
||||
*
|
||||
* Note that this function will update _at least_ the rectangles specified,
|
||||
* but this is only intended as an optimization; in practice, this might
|
||||
* update more of the screen (or all of the screen!), depending on what
|
||||
* method SDL uses to send pixels to the system.
|
||||
*
|
||||
* \param window the window to update
|
||||
* \param rects an array of SDL_Rect structures representing areas of the
|
||||
* surface to copy, in pixels
