GSdx: that damned different pixel center of dx10... this one should fix the screen edge and other strange artifacts that appeared in non-native resolution.

GSdx: Applied normalization of UV in the DX9 texture repeat shader, allowing it to be re-enabled. Fixes massive slowdown in the Xenosaga 2 opening menu (Issue 262 / DX9 only) [note: collective fix uncovered by sudonim, feal87, and drk||raziel -- I'm just the patching boy]

GSdx: Even more alpha test voodoo magic, it must be nailed now!
...
And there is even an explanation.
The tfx functions calculate At * Af >> 7, which means modulating by 0x80 should return At as the result.
With the evil floating point pixel shader however 0x80 translates to 128/255 (0.502), not exactly 0.5, modulation as At' * Af' * 2 (' means 0 - 1.0 range) is not the same as with integers.
At' = Af' = 0.502
At' * Af' * 2 = 0.504
If the alpha test happens to be "not equal to 0x80", then abs(0.504 - 128/255) < 0.5/255 will just miss.
Solution is to re-scale those values to the integer range, do the calculations, and then back to float again, but in the end it just simplifies down to At' * Af' * 255/128, doh...
At * Af >> 7 => ((At' * 255) * (Af' * 255) / 128) / 255 => At' * Af' * 255/128
At' = Af' = 0.502
0.502 * 0.502 * 255/128 = 0.502 (w00t!)

GSdx: 3.4.9. Texture Function => Decal/TCC=RGB: Av = At (gs_user v3 and v5) or Av = Af (v6)? Seems it was Af... Sonic unleashed was one of the games relying on this setting, could not find any other yet. Also removed the green stripes, shadow sw-mode only.

GSdx: fixed Issue 182 (narrowed the neq alpha test range to +/-0.4f/255, scream if something broke), and re-enabled something to make DATE faster (counting min/max of the vertices outperforms stencil buffer clearing when there are many small primitive batches).
