Release notes 

- This release adds support for OpenGL ES and EGL in GLEW lib.

- At present either purely desktop GL or purely OpenGL ES is supported.

- Name of the output library(libGLEW.so) is same in both Desktop and ES version.

- glewinfo and visualinfo utilities have been updated to support ES.

- A file "Makefile.arm-linux" is added to compile the 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. invoke command :

  make MAKE_FOR_ES=yes

Issues:

- Since EGL may not be always used with OpenGL ES or platform specific modification might happens in EGL. Its usage has to be made optional.

- There is no generic GLEW lib which support both OpenGL ES and desktop OpenGL.Planned for next release.
- Makefiles needed to handle various platforms.

    EGL extensions and core spec supported can be queried using eglewIsSupported or eglewContextIsSupported
    glewInfo and visualinfo are modified to add support for ES

    EGL function pointers and variables are defined in glew.c

commit 99652117f22881c97aa00c8a5271970cb44131b8
Author: Shariq <email address hidden>
Date: Sun Jun 19 07:45:48 2011 -0400

    Modifed glew_head.c to include loading of ES libs in case of Linux.
    Added some macros and include the eglew.h header for GLEW_ES_ONLY case.

    Still need to properly do the loading of the lib.
    Present one is added to do initial testing.

commit 6abbeb7a057ae402dc059aa52aed3b2b00a3e1c8
Author: Shariq <email address hidden>
Date: Sun Jun 19 07:14:14 2011 -0400

    GLES extensions and core specs are initailized and whether these are supported can be queried

    Some extensions are common to both OpenGL and OpenGL ES.
    These extensions are moved from ES to 'common' folder so that there are not initialized twice.
    Once glew.c is created these extensions are moved back.
    For this two script are added:
    move_common_ext.sh and move_back_common_ext.sh

    glesew.h checks that it should be included via glew.h
    fixed GL_OES_single_precision by adding GLclampd definition
