Description
This is extension, along with related platform extensions, allows
applications to take exclusive control of displays associated with a
native windowing system. This is especially useful for virtual reality
applications that wish to hide HMDs (head mounted displays) from the
native platform’s display management system, desktop, and/or other
applications.

Issues
1) Should this extension and its related platform-specific extensions
leverage VK_KHR_display, or provide separate equivalent interfaces.
RESOLVED: Use VK_KHR_display concepts and objects.
VK_KHR_display can be used to enumerate all displays on the system,
including those attached to/in use by a window system or native
platform, but VK_KHR_display_swapchain will fail to create a swapchain
on in-use displays. This extension and its platform-specific children
will allow applications to grab in-use displays away from window systems
and/or native platforms, allowing them to be used with
VK_KHR_display_swapchain.
2) Are separate calls needed to acquire displays and enable direct mode?
RESOLVED: No, these operations happen in one combined command.
Acquiring a display puts it into direct mode.
