Function sdl2_sys::SDL_SetClipRect

pub unsafe extern "C" fn SDL_SetClipRect(
    surface: *mut SDL_Surface, 
    rect: *const SDL_Rect
) -> SDL_bool

Sets the clipping rectangle for the destination surface in a blit.

If the clip rectangle is NULL, clipping will be disabled.

If the clip rectangle doesn't intersect the surface, the function will return SDL_FALSE and blits will be completely clipped. Otherwise the function returns SDL_TRUE and blits to the surface will be clipped to the intersection of the surface area and the clipping rectangle.

Note that blits are automatically clipped to the edges of the source and destination surfaces.
