Showing CPU vs GPU computation difference using fractals

The black fractal is rendered using shaders that run on the GPU while the red one uses just the CPU. After both
are rendered you can see the time it took for each. Sometimes the CPU shader will appear quicker, even though the
times show the opposite. I believe this happens because of the slight overhead for translating WebGL API calls and shaders to
your OS graphics API, though I might be wrong, if you know why this is don't be a stranger. This might be better explained here.
