title: iOS using GL_RGBA8
body: <p>Is there a way to use <code>GL_RGBA8</code> on the iPhone/iPad? My textures show up as blank when I try to use <code>GL_RGBA8_OES</code> instead. <code>GL_RGBA</code> is causing problem when using transparency.</p>
  
  <p>I haven't tried it on the real device, only in the simulator.</p>
