SYNOPSIS

       #include <SDL3/SDL_render.h>

       bool SDL_SetRenderViewport(SDL_Renderer *renderer, const SDL_Rect *rect);

DESCRIPTION

       Drawing  will  clip  to this area (separately from any clipping done with SDL_SetRenderClipRect), and the
       top left of the area will become coordinate (0, 0) for future drawing commands.

       The area's width and height must be >= 0.

       Each render target has its own viewport. This function sets the viewport for the current render target.
