  Draft spec for ANGLE_platform_angle_d3d
  
  This is the initial draft of a spec that extends
  EGL_EXT_platform_base to allow choosing a particular ANGLE D3D
  backend.

  Number
  
      EGL Extension XXX
  
  Extension Type
  
      EGL client extension
  
  Dependencies
  
      Requires EGL_EXT_client_extensions to query its existence without
      a display.
  
      Requires EGL_EXT_platform_base.
  
      This extension is written against the wording of version 9 of the
      EGL_EXT_platform_base specification.
  
  Overview
  
      This extension defines how to create EGL resources from resources using
      the functions defined by EGL_EXT_platform_base.
  
  New Types
  
      None
  
  New Procedures and Functions
  
      None
  
  New Tokens
  
      Accepted as the <platform> argument of eglGetPlatformDisplayEXT:
  
          EGL_PLATFORM_ANGLE_D3D_ANGLE                       0x3201
  
      Accepted as an attribute name in the <attrib_list> argument of
      eglGetPlatformDisplayEXT:
  
          EGL_PLATFORM_ANGLE_D3D_TYPE_ANGLE                  0x3202
  
      Accepted as values for the EGL_PLATFORM_ANGLE_D3D_TYPE_ANGLE attribute:
  
          EGL_PLATFORM_ANGLE_D3D_TYPE_D3D9_ANGLE             0x3203
          EGL_PLATFORM_ANGLE_D3D_TYPE_D3D11_ANGLE            0x3204
          EGL_PLATFORM_ANGLE_D3D_TYPE_D3D11_WARP_ANGLE       0x3205
  
  Additions to the EGL Specification
  
      None.
  
  New Behavior
  
      To determine if the EGL implementation supports this extension, clients
      should query the EGL_EXTENSIONS string of EGL_NO_DISPLAY.
  
      To obtain an EGLDisplay backed by a ANGLE D3D display, call
      eglGetPlatformDisplayEXT with <platform> set to
      EGL_PLATFORM_ANGLE_D3D_ANGLE.
      
      The <native_display> parameter is of type EGLNativeDisplayType. If
      <native_display> is EGL_DEFAULT_DISPLAY a default display is returned.
      Multiple calls with the same <native_display> will return the same
      EGLDisplay handle. The value of EGL_PLATFORM_ANGLE_D3D_TYPE_ANGLE, if any,
      is ignored if there was previously a EGLDisplay successfully created for a
      given value of EGLNativeDisplayType.
      
      If no <attrib_list> is specified, a D3D9 device is created. Otherwise, the
      value of EGL_PLATFORM_ANGLE_D3D_TYPE_ANGLE should be:
        - EGL_PLATFORM_ANGLE_D3D_TYPE_D3D9_ANGLE for D3D9 hardware,
        - EGL_PLATFORM_ANGLE_D3D_TYPE_D3D11_ANGLE for D3D11 hardware,
        - EGL_PLATFORM_ANGLE_D3D_TYPE_D3D11_WARP_ANGLE for D3D11 WARP.
          
      If no display matching the requested <native_display> or of the type
      requested by the value of EGL_PLATFORM_ANGLE_D3D_TYPE_ANGLE is available,
      EGL_NO_DISPLAY is returned. No error condition is raised in this case.
