SSAO downsampled with blur

Hi there!

The next step with my SSAO is to use more complex model, in this case BigDady2 of biosock, thanks Llorens ;)

I use the SSAO result and a blur shader with one 2x downsampled.

SSAO with Blur, BigDady2 model for learning purpose

1. Original SSAO in fullscreen
2. SSAO texture downsampled width and height >> 2
3. Combine 1 + 2 * 0.5 :)

The result is a soft texture without noise. This noise exist because I use only 16 samples per pixel in SSAO pass.
