7. What is GLEW
| OpenGL Extension Wrangler Library
| Makes it easy to access OpenGL extensions
available on a particular system
| Provide efficient run-time machinism
| Application needs only to include glew.h and run a
glewInit()

16. Configure Open GL
| Open Microsoft SDKs folder path:
C:Program FilesMicrosoft
SDKsWindowsv7.0A
| Now copy the content of the files from the
freeglut and glew here in include and lib
directory. Such as:
Open lib folder of freeglut and copy freeglut.lib and
paste it inside the Lib of v7.0A
Open include folder of freeglut and copy header files
form gl folder to Gl folder of of v7.0A
Do same thing for the glew and for DevC++
