  Add EGL_ANGLE_workaround_control extension.
  
  This extension is used to query strings from an array based on index,
  which will be used to query all the information about workarounds in
  ANGLE.

      EGL Extension #XXX
  
  Extension Type
  
      EGL device extension
  
  Dependencies
  
      This extension is written against the wording of the EGL 1.4
      Specification.
  
  Overview
  
      This extension defines a method to query a string describing
      properties of the EGL client or of an EGL display connection
      which are looked up via the property name and index.
  
  IP Status
  
      No known claims.
  
  New Types
  
      None.
  
  New Procedures and Functions
  
      const char *eglQueryStringiANGLE(
          EGLDisplay dpy,
          EGLint name,
          EGLint index);
  
  New Tokens
  
      Accepted as a queried <name> in eglQueryStringiANGLE:
  
          EGL_WORKAROUND_NAME_ANGLE          0x3460
          EGL_WORKAROUND_CATEGORY_ANGLE      0x3461
          EGL_WORKAROUND_DESCRIPTION_ANGLE   0x3462
          EGL_WORKAROUND_BUG_ANGLE           0x3463
          EGL_WORKAROUND_ENABLED_ANGLE       0x3464
  
  Additions to the EGL 1.5 Specification
  
      Add the following to the end of section 3.3 "EGL Queries":
  
          const char *eglQueryStringiANGLE(EGLDisplay dpy,
              EGLint name, EGLint index);
  
      eGLQueryStringiANGLE returns a pointer to a static, zero-
      terminated string describing some aspect of the EGL
      implementation running on the specified display, from an array of
      strings. name may be one of EGL_WORKAROUND_NAME_ANGLE,
      EGL_WORKAROUND_CATEGORY_ANGLE, EGL_WORKAROUND_DESCRIPTION_ANGLE,
      EGL_WORKAROUND_BUG_ANGLE, or EGL_WORKAROUND_ENABLED_ANGLE. Index
      must be a valid index to access into the array of strings.
          The EGL_WORKAROUND_NAME_ANGLE array contains strings that
      describe the name of each workaround available in the display.
          The EGL_WORKAROUND_CATEGORY_ANGLE array contains strings
      with corresponding indices to the array of names. Each string
      describes the category of the workaround at the specified index.
          The EGL_WORKAROUND_DESCRIPTION_ANGLE array contains strings
      with corresponding indices to the array of names. Each string
      describes the workaround at the specified index.
          The EGL_WORKAROUND_BUG_ANGLE array contains strings
      with corresponding indices to the array of names. Each string
      describes the bug related to the workaround at the specified
      index.
          The EGL_WORKAROUND_ENABLED_ANGLE array contains strings
      with corresponding indices to the array of names. Each string has
      the value "true" if the workaround is currently enabled, or
      "false" if the workaround is currently disabled.
  
      Errors
  
      On failure, NULL is returned.
      An EGL_BAD_DISPLAY error is generated if dpy is not a valid
      display.
      An EGL_BAD_PARAMETER error is generated if name is not one of the
      values described above.
      An EGL_BAD_PARAMETER error is generated if index is not within
      the valid range of indices for the array.
  
  Issues
  
      None
