Also disabled the gsdx AF options for the OGL renderer (because it's not implemented for that yet).

Adds anisotropic texture filtering (1x-16x) to the hardware settings. Enhances the visual quality of textures that are at oblique viewing angles.
Anisotropic filtering is automatically disabled if: 8-bit textures are enabled.

Now, a note about the actual issue. Destination alpha tests can be used on the GS as one of the workarounds for a lack of stencils. If you use a destination alpha test and leave alpha writing on, the GS will only write each pixel until you write an alpha value which would fail the test. This works to a point in gsdx without further hacking, but that point is when within a single batch of primitives the same pixels are written multiple times and the destination alpha test is expected to update. I did experimentally make a tight loop updating the stencil with a draw then drawing for one primitive at a time, but it was prohibitively slow (over 80% fps loss, you really don't want to know).
Destination alpha testing cannot be directly implemented in D3D9 or D3D10, but (probably) can in D3D11 (with a speed hit for sure, but I doubt it'll be 80%). I'll be getting a new graphics card and looking into that.
And before some idiot says it, the answer is no. OpenGL does not help.

This may make gsdx slightly slower for everyone (I don't know an easy way to restrict this to affected systems), especially if using 8-bit textures.

Another refinement to the Wild Arms hack by KrossX.
The hack now only applies to one kind of geometry (sent using the unpacked UV handler).
This works nicer in Wild Arms as it fixes "jumpy" characters.

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.

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

- GSWnd is not implemented, no config dialogs either
- no output, just the null device
- threading classes were not tested (my first experience with pthread)

32-bit depth buffers for D3D9 users if available. Lots of code shuffling for reasons I don't even remember. Stuff. Pretty much just the 32-bit depth buffers. That's good though, you don't have to envy D3D10 users half as much now.

Fixes shadows in Ico and Shadow of the Colossus and hopefully fixes more effects in other games.

Also, screw you, Stroustrup! You don't make me cast short to int, so don't make me cast int to an enum! PS: arithmetic operators, you stingy bastard.

* Removed GSTextureFX classes
* Built shaders right into GSState classes, using GSStateDX as an interface, so that all shader caches get auto-destroyed along with GSState.
In addition to being a bit of a code cleanup, it should be a bit more efficient too since all of the extra dereferences to GSState from GSTextureFX have been removed. :)

- 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
