+ 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.
