GLEssentials

================================================================================
DESCRIPTION:

This sample provides an example of some of the techniques described in the 
"OpenGL Essential Design Practices" WWDC 2010 session.  There are usages of 
Vertex Buffer Objects (VBOs), Vertex Array Objects (VAOs),  Framebuffer Objects 
(FBO), and GLSL Program Objects.  It creates a VAO and VBOs from model data 
loaded in.  It creates a texture for the model from image data and GLSL shaders 
from source also loaded in.   It also creates an FBO and texture to render a 
reflection of the model.  It uses an environment mapping GLSL program to apply 
the reflection texture to a plane.  This sample also demonstrates sharing of 
OpenGL ES source code for iPhone OS and OpenGL source code for Mac OS X.  
Additionally, it demonstrates how to obtain and use an OpenGL 3.2 rendering 
context on Mac OS X Lion.
