title: Book on OpenGL _2D_ programming?
body: <p>I need to draw hundreds (maybe thousands!) of images to the screen.  Majority of the work is going to be in 2d.  It'll use some 3d for camera, transforms, rotating scene, but mainly concerned with 2d performance.  Any book on this specific subject?</p>
  
  <p>1) Learn best practices in 2d OpenGL programming</p>
  
  <p>2) Shaders and fancy effects</p>
  
  <p>3) Optimizing 2d rendering operations.</p>
