Plan - questions about course, hw1, hw2?  
     - go over simple.cpp OpenGL example, bubbles.cpp, 
     - Nate Robbins OpenGL tutorials

Material to cover
     - coordinates in OpenGL, transformations, lighting
     - display device - raster images, pixels, RGBA
     - transformations, transformation matrices

Basic graphics/windows programming
  * set up callback functions
  * windows or whatever calls them when needed, whenever whatever event happens.
  

Matrices...
  * projection matrix...
  * modelview matrix...
  * changes to modelview matrix kept in stack,
    any time draw an object, all those get combined to transform it's position.
  * OpenGL keeps matrices for us about transformations...
