[SDL2/Windows]-SDL_RenderSetClipRect() & Window Resizing?

Hi,

We are working on converting our word game from SDL1 to SDL2.
We are now in the process of adding "Dirty Rectangle" drawing optimization to it.
(needed to improve game speed on old Windows XP computers which we decided to support)

SDL_RenderSetClipRect() seems to be the command we need.
But what happens when the game's window is resized?
Do we need to recalculate the SDL_Rect based on the new size of the game's window?

Thanks!
