gabest11 cc3130660a GSdx:
- Automatic texture filtering should be ok now, occasionally point filtering was used. Tested it on the ps2 and figured with no mip levels LoD and minification settings are just ignored altogether.
- Also run a few tests on the gather instruction with the reference rasterizer and found a fatal flaw with it. It returns the four samples for bilinear sampling (in a funny order, which isn't documented of course, x = bl, y = br, z = tr, w = tl), but there is no way to guess which four were selected exactly. Due to some hidden rounding error it might grab different texels than I would when calculating the position of the upper-left texel, of which the fractional part is be used for the interpolation. When the texel positions do not match it leaves annoying discontinuity errors. Oh well...

- trying the dx10.1-only "gather" shader instruction for palletized lookups ("8-bit texture" mode), saves 4 instructions which isn't much but still... (not tested, don't have ati)
- may fix the intel gma "no output" bug (don't have gma either :P)
- and the usual small code optimizations

gabest11 f9f056d581 GSdx: fixing/breaking things again... palletized texture lookup can be done by pixel shader now (selectable, off by default), if you have a fast card it may help with texture heavy games, otherwise it is only going to be slower.

gabest11 b284fae2d5 GSdx: moved around some code and optimized texture caching a bit, there may be a slight speed-up in hw mode for those games that use many textures.

Jake.Stine 95ff8e3a98 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]

gabest11 3e12966919 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!)

gabest11 c64691811a 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.

gabest11 1245659eee 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).
