SSAO samples vs quality

[Thomas]

Quick descriptions:

Quality:
This is the size of the ssao buffer, which at medium is 1/4 of screen size (eg 400x300 on a 800x600 resolution) and at high it is the same size. This makes high ssao less blurry and block but 4 times slower!

Samples:
Ssao is performed by check testing the depth around each pixel on the screen. 1 Sample = 1 test. The more samples the less noise. Note that since the samples are often pretty near the pixel, at certain resolutions there is NO difference between 32 and high samples sizes, because after 32 samples, there is no more pixels left to test!

Hope that clears some stuff out!
