  Number
  
      EGL Extension XXX
  
  Extension Type
  
      EGL client extension
  
  Dependencies
  
      Requires ANGLE_platform_angle_d3d.
  
  Overview
  
      This extension enables the selection of a graphics adapter to back D3D.
  
  New Types
  
      None
  
  New Procedures and Functions
  
      None
  
  New Tokens
  
      Accepted as an attribute name in the <attrib_list> argument of
      eglGetPlatformDisplayEXT:
  
          EGL_PLATFORM_ANGLE_D3D_LUID_HIGH_ANGLE          0x34A0
          EGL_PLATFORM_ANGLE_D3D_LUID_LOW_ANGLE           0x34A1
  
  Additions to the EGL Specification
  
      None
  
  New Behavior
  
      To request a display that is backed by a specific graphics adapter,
      EGL_PLATFORM_ANGLE_D3D_LUID_HIGH_ANGLE and/or
      EGL_PLATFORM_ANGLE_D3D_LUID_LOW_ANGLE should be set to the high part and low
      part of the adapter's LUID. If only one attribute is specified, the other is
      assumed to be zero.
  
      If the high part and low part combined is zero, an EGL_BAD_ATTRIBUTE error
      is generated and EGL_NO_DISPLAY is returned.
  
      If the LUID specified doesn't match any adapters on the system, the default
      adapter is used.
  
      If EGL_PLATFORM_ANGLE_D3D_LUID_HIGH_ANGLE and/or
      EGL_PLATFORM_ANGLE_D3D_LUID_LOW_ANGLE is included in the <attrib_list>
      argument of eglGetPlatformDisplayEXT and EGL_PLATFORM_ANGLE_TYPE_ANGLE is
      not set to EGL_PLATFORM_ANGLE_TYPE_D3D11_ANGLE, an EGL_BAD_ATTRIBUTE error
      is generated and EGL_NO_DISPLAY is returned.
