Texture channel 0 has a 512x2 texture with audio samples. For now,
fill it with dummy data (ascending slope), so we can see some

- Fix uniform name for iFrame
- Move timer initialization to main loop, so we don't measure

Unbind the FBO+texture after initialization, bind it before
rendering, unbind it after, re-bind the texture to scrape the
data, unbind the texture.
