  Additions to the EGL 1.4 Specification:
  
      To export VkImage from an EGLImage, a new API is required.
  
      The new entrypoint
          EGLBoolean eglExportVkImageANGLE(
              EGLDisplay dpy,
              EGLImageKHR image,
              void* vk_image,
              void* vk_image_create_info);
  
      is used to retrieve the VkImage and VkImageCreateInfo of the EGLImage.
      The VkImage is stored into <vk_image> pointed memory, and VkImageCreateInfo
      is filled into <vk_image_create_info> pointed memory.
