      EGL Extension #28
  
  Dependencies
  
      This extension is written against the wording of the EGL 1.4
      Specification. 
  
  Overview
  
      This extension allows querying pointer-sized surface attributes,
      thus avoiding problems with coercing 64-bit pointers into a 32-bit
      integer.
  
  New Types
  
      None
  
  New Procedures and Functions
  
      EGLBoolean eglQuerySurfacePointerANGLE(
                          EGLDisplay dpy,
                          EGLSurface surface,
                          EGLint attribute,
                          void **value);
  
  New Tokens
  
      None
  
  Additions to Chapter 3 of the EGL 1.4 Specification (EGL Functions and Errors)
  
      Add to the end of the paragraph starting with "To query an
      attribute associated with an EGLSurface" in section 3.5.6,
      "Surface Attributes":
  
      "If the attribute type in table 3.5 is 'pointer', then
      eglQuerySurface returns EGL_FALSE and an EGL_BAD_PARAMETER error
      is generated.  To query pointer attributes, call:
  
           EGLBoolean eglQuerySurfacePointerANGLE(
                               EGLDisplay dpy,
                               EGLSurface surface,
                               EGLint attribute,
                               void **value);
  
       eglQuerySurfacePointerANGLE behaves identically to eglQuerySurface,
       except that only attributes of type 'pointer' can be queried.
       If an attribute queried via eglQuerySurfacePointerANGLE is not
       of type 'pointer', then eglQuerySurfacePointer returns EGL_FALSE
       and an EGL_BAD_PARAMETER error is generated."
