Fix 2583.

Fixes 2583. It seems that triangle-util is the only example that fell into this trap, but there are a lot of examples, so I can't say for certain.

I noticed this as well and yes this is the only example that suffers from this I think. But I would have preferred it if you did it the same way every other example does it, that is, update the viewport when recreating the swapchain.

The docs of Viewport are talking about the viewport(s) you pass when creating ViewportState. The idea is that you use ViewportState::default() when creating the pipeline with dynamic viewport state. The fact that this default exists at all is IMO a footgun, but unrelated to this issue. You can forget to update the viewport using static or dynamic viewport state; it's entirely unrelated to this.

All in all I think the only change should be this:

                         // Whenever the window resizes we need to recreate everything dependent
                         // on the window size. In this example that
                         // includes the swapchain, the framebuffers
                         // and the dynamic state viewport.
                         rcx.framebuffers =
                             window_size_dependent_setup(swapchain_images, &rcx.render_pass);
+                        rcx.viewport = window_size.into();

Cool, thanks!

Awesome, thank you!
