title: iPhone, rotated + EAGLView, rotated =
body: <p>...frustration.  I want my game to be run only in landscape mode.  I have added the appropriate key/value to the Info.plist file that forces the device orientation to be correct at launch.</p>
  
  <p>I'm now trying to rotate the OpenGL coordinate space to match that of the device.  I'm trying to use the code I found <a href="https://stackoverflow.com/questions/611468/in-opengl-es-how-do-i-convert-screen-coordinates-to-world-coordinates">here</a>, but it's not working.  My test case draws a square at the center, and with <em>all</em> of that code included, I see nothing drawn; if I comment out the 2nd part (only setting the GL_PROJECTION matrix mode), the coordinate system <em>does</em> appear to be correct.  But I'd like it rotated as well.  I'm a little puzzled on how to do this, as well as setting up the view nib correctly as well.  Tips, please?</p>
  
  <p>Also, in the future, I'm going to be swapping out the EAGLView with another UIView subclass; is doing this going to require anything different?</p>
  
  <p>Thanks!
