ramapcsx2 b25aec19c1 GSdx:
Adding KrossX's Wild Arms text alignment hack to the new dialog box. This hack is actually very interesting for a number of games. It should work well in cases where game designers adjusted everything pixel perfect for the GS, that usually breaks with upscaling. 
It should be generalized and renamed later.

ramapcsx2 954e7906ed GSdx: Added the color control functionality known as "ShadeBoost". Thanks to KrossX for initial converting / GUI work and Pseudonym for normalizing / fixing the maths.
Note: Not sure if it should be shader #7 or smth else :p

Committing a hack KrossX prepared (thanks) ;)
It can be used to fix bad character sprites in Gust games.

* Use the new map interface/separate texture coordinate inside shader
* support new format on texture

Note: it is quite instable with various crashes and GL error but at least it compiles now :p

gabest11 bd12a8b7b3 GSdx: silent hill shattered memories purple street light fix, not block aligned filled rects were not correctly masked, may also fix games which store texture data in the alpha channel but use 24-bit target buffers (or just mask it in every time) and draw a lot of those unaligned rects. (tested many .gs dumps, very rare combination)

* Fix the Geomtry shader to output 2 triangles for quad primitive (ie 2R rendering)
- There is an AMD  driver bug on geomtry shader input interface (well could be the spec too). Tell me if it still working on nvidia
* Add a workaroung to a previous AMD bug. It is impossible to unattach a shader so destroy the full shader pipeline...
* Be more strict on FBO management. Would optimize it later
* use a texture insted of a render buffer for depth-stencil management.
* add more dumping capabilities (in particular depth buffer)

* implement the saving of texture (take bmp SW code)
* fix the missing "enable attribute code" and the typo in glsl. It works now !!!
* rework a little texture to pack texture into a temporay buffer when src pitch != dst pitch
* try to replace sdl with pure xlib (not yet enabled by default but it seems to work)

Note there still a minor issue, coordinate are different between DX and OGL (upper-left vs lower-left) so the image is inversed.

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...

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.
