Sure. Would you consider separate PR updating the SDL build matching the glfw build or should I just leave it out?

Yep, currently `docking` head crashes with the glfw vulkan example and resize  Looking at this now since my next work is getting #3372 working with docking.

Okay I updated, cherry-picked @ocornut `a65a6cae41d172c01d813da310e6b25d4fce5d80` and retargeted to `docking`. @hinxx Thank you for trying this out! As of this comment resizing the main window works, resizing any child windows...

Yeah, it works fully with viewports! I think this is good to go now. 

Oh drat I forgot that it's possible that `vkAcquireNextImageKHR` could also return out of date. That's a rarer case though what @hinxx uses for a window manager trips it immediately....

Should be better now!

That one has me concerned. Viewports are rendered in two functions RenderWindow and SwapBuffers. RenderWindow does a render pass and SwapBuffers does the page flip. I'm trying to think through...

Okay I went with nulling out the draw data approach. Hopefully that's the last of them.
