  Number
  
      EGL Extension XXX
  
  Extension Type
  
      EGL client extension
  
  Dependencies
  
      Requires ANGLE_platform_angle.
  
      EGL_ANGLE_display_power_preference interacts with this extension.
  
  Overview
  
      This extension enables the selection of a graphics device to back
      an ANGLE EGLDisplay.
  
  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_DEVICE_ID_HIGH_ANGLE          0x34D6
          EGL_PLATFORM_ANGLE_DEVICE_ID_LOW_ANGLE           0x34D7
          EGL_PLATFORM_ANGLE_DISPLAY_KEY_ANGLE             0x34DC
  
  Additions to the EGL Specification
  
      None
  
  New Behavior
  
      To request a display that is backed by a specific graphics device,
      EGL_PLATFORM_ANGLE_DEVICE_ID_HIGH_ANGLE and/or
      EGL_PLATFORM_ANGLE_DEVICE_ID_LOW_ANGLE should be set to the high part and
      low part of the device's ID. If only one attribute is specified, the other
      is assumed to be zero. The device's ID is specific to the platform that
      ANGLE is running on, but should fit into one 64-bit value.
  
      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 ID specified doesn't match any devices on the system, the device
      is selected as described in the EGL_ANGLE_display_power_preference extension.
  
      To select a distinct display on a graphics device that may already have
      an existing display in ANGLE's cache, use EGL_PLATFORM_ANGLE_DISPLAY_KEY_ANGLE
      to add a key to the cache entry for this display. The same cached display can
      be re-requested by specifying the same cache value. If this parameter is not
      included, the default value used will be 0.

  Revision History
  
      Version 3, 2023-02-15
        - Add EGL_PLATFORM_ANGLE_DISPLAY_KEY_ANGLE to allow selection of
          multiple EGLDisplays from the same graphics device.
  
      Version 2, 2022-04-09 (Kimmo Kinnunen)
        - Describe interaction with EGL_ANGLE_display_power_preference,
          EGL_ANGLE_platform_angle_device_id takes precedence.
  
      Version 1, 2021-12-14 (Jonah Ryan-Davis)
        - Initial draft, based on EGL_ANGLE_platform_angle_d3d_luid
