gabest11 65b90bce83 GSdx: there was a bug in unaligned 4/8 bit transfer, small texture glitches may be fixed (simpson game, car logos in gt4).

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 3b22adc4b3 GSdx: converted a few template classes to pointers and virtual functions, the dll got more than 100k smaller, since there were many changes, backup your old version first :P

Jake.Stine 6ebfae8ef1 Re-Added eol-style:native properties to the repository. The settings got lost when we merged from Playground to Official.
Added interface.cpp (plugin/pcsx2 interface) and savestate.cpp to SPU2ghz, to help clean up SPU2.cpp.
