From f7212fd20236827c0fca8b5c76486e60de2db535 Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>
Date: Thu, 4 Nov 2010 19:45:52 +0100
Subject: Adding patches for gluegen interoperability and adding some
 extensions:

    - eglplatform.h: if platform not recognized, use 'void pointer' for EGLNativeDisplayType, EGLNativeWindowType and EGLNativePixmapType
    - egl.h: adding ifndef core extension for gluegen and eglGetProcAddress
    - eglext.h: adding EGL_NV_texture_rectangle, EGL_NV_system_time, EGL_NV_omx_il_sink, EGL_RMSURFACE_NV
