Release notes 

This release contains GLEW lib which supports OpenGL and OpenGL ES.
The glew.h header now contains enums and entry points for both OpenGL and OpenGL ES.
The use of egl from glew lib is made optional, now user can use either egl.h or eglew.h

- A file "Makefile.arm-linux" is present to compile glew for ARM linux

  Steps for building glew for ARM-Linux ES 2.0:

  1. export following environment variables:

   COMPILER_PATH : Path of the compiler

   INC_PATH : Include files path

   LIB_PATH : Opengl/egl/x11 library path

   ADDITIONAL_LIB_DEPENDENCY_PATH: Path for any additional dependencies of the libs.

   2. Build command :
 - To biuld glew for OpenGL ES 2.0 along with EGL(need to include eglew.h):

   make BUILD_GLEW_ES20=yes BUILD_GLEW_EGL=yes

 - To build glew for OpenGL ES 2.0 without EGL(need to include egl.h):

   make BUILD_GLEW_ES20=yes

 - To build glew for Desktop

   make

Issues:
  - glewinfo does not print list of OpenGL ES extensions supported.

commit 9ff09fd397f11e09fc8fdd3fe9519d32f4e3f670
Author: Shariq <email address hidden>
Date: Thu Aug 18 03:28:38 2011 -0400

    Creation of context and EGL related extensions query are done for glewinfo
    The OpenGL ES extension query are missing

Author: Shariq <email address hidden>
Date: Thu Aug 18 02:38:07 2011 -0400

    Modifications for glewinfo.c file.
    The egl(eglew.h or egl.h) can be used with ES in glewinfo.
    Many of the functions are dummy functions;need to be initilized.

    visualinfo.c will display all the visuals information using egl function call for ES.

    Use of eglew.h is made optional in glew lib. User can also use their own specific egl.h file
    When GLEW_USE_EGL is defined in case of OpenGL ES then eglew.h is used.
    Also GLEW_USE_LIB_ES is defined for the case when ES is being used to link the lib
    If GLEW_USE_LIB_ES11 or GLEW_USE_LIB_ES20 flag is passed from the Makefile then only it will defined.

    Instead of moving the common extension files, the common folder is used to create the glew.c file

    Initialization functions call are called properly.
    ES core version initialization functions call are different in general and ES ONLY case as the functions are different.

    ES core spec variables and function pointers are initialized for general case.
    In the general case supporting both OpenGL and ES,the ES core spec has variables from OpenGL specs also.
    So a file is added which already contains the initialization functions instead of using make_init.pl

commit 126db1eea154476cd5fd9503817823e4d4fe396b
Author: Shariq <email address hidden>
Date: Wed Aug 17 11:07:37 2011 -0400

    Fixed EGL_NV_system_time extension.
    EGLuint64NV definition was not present.

Author: Shariq <email address hidden>
Date: Wed Aug 17 10:57:17 2011 -0400

    Moved Khronos specific types and definitions(mostly from khrplatform.h) from glesew.h to glew.h.
    It is done so that the types and definitions can be shared by both the files.

    Added OpenGL ES related variables and functions pointer to GLEW context structure in glew.h

Author: Shariq <email address hidden>
Date: Fri Aug 12 01:38:28 2011 -0400

    OpenGL ES related function pointers and variables are defined in glew.c.

Author: Shariq <email address hidden>
Date: Fri Aug 12 01:04:45 2011 -0400

    Modification start to create glew lib supporting both desktop OpenGL and ES.

    glew.h contains the core and extensions for ES.
    Inside the folder 'core' the ES related core spec are added in folder 'es'.
    This is needed as we need to remove those enum and functions which are already defined by OpenGL.

    Also update_ext_es.sh has been modified to handle the extensions GL_NV_read_buffer_front and GL_NV_read_buffer.
