title: Resizing an image using OpenGL
body: <p>I'd like to resize an image using OpenGL. I'd prefer it in Java, but C++ is OK, too.</p>
  
  <p>I am really new to the whole thing so here's the process in words as I see it:</p>
  
  <ol>
  <li>load the image as a texture into OGL</li>
  <li>set some stuff, regarding state &amp; filtering</li>
  <li>draw the texture in different size onto another texture</li>
  <li>get the texture data into an array or something</li>
  </ol>
  
  <p>Do you think if it would be faster to use OpenGL and the GPU than using a CPU-based BLIT library?</p>
  
  <p>Thanks!</p>
