Description
The VK_KHR_xlib_surface extension is an instance extension.
It provides a mechanism to create a VkSurfaceKHR object (defined by
the VK_KHR_surface extension) that refers to an X11 Window,
using the Xlib client-side library, as well as a query to determine support
for rendering via Xlib.

Issues
1) Does X11 need a way to query for compatibility between a particular
physical device and a specific screen? This would be a more general query
than vkGetPhysicalDeviceSurfaceSupportKHR; if it returned
VK_TRUE, then the physical device could be assumed to support
presentation to any window on that screen.
RESOLVED: Yes, this is needed for toolkits that want to create a VkDevice before creating a window. To ensure the query is reliable, it must be made against a particular X visual rather than the screen in general.
Version History
- 
Revision 1, 2015-09-23 (Jesse Hall) - 
Initial draft, based on the previous contents of VK_EXT_KHR_swapchain (later renamed VK_EXT_KHR_surface). 
 
- 
- 
Revision 2, 2015-10-02 (James Jones) - 
Added presentation support query for (Display*, VisualID) pair. 
- 
Removed “root” parameter from CreateXlibSurfaceKHR(), as it is redundant when a window on the same screen is specified as well. 
- 
Added appropriate X errors. 
- 
Adjusted wording of issue #1 and added agreed upon resolution. 
 
- 
- 
Revision 3, 2015-10-14 (Ian Elliott) - 
Renamed this extension from VK_EXT_KHR_x11_surface to VK_EXT_KHR_xlib_surface. 
 
- 
- 
Revision 4, 2015-10-26 (Ian Elliott) -
