Here is a guidance for how to implement this.

Currently vkQueuePresentKHR returns VK_SUBOPTIMAL_KHR.
Bgfx handles this with swapchain buffer recreation. This recreation happens every frame so this
effects performance very badly.
For our test scene the frame was 30-35 fps with prerotation implemented the framerate went up to 60-70 fps.
