Explanation, because this gives me a headache and this might save someone else one (or I might be wrong and they might see why): in D3D10, 0.0 points to the centre of the leftmost texel and 1.0 points one texel to the right of the rightmost texel, so to map a UNORM uniformly across a texel we need to multiply the input by (w-1)/w. In D3D9 0.0 points to the left edge of the leftmost texel and 1.0 to the right edge of the rightmost texel so after the multiplication we add 1/2w.
Actual texture sampling is probably not right for at least one of D3D9 and D3D10, but this headache is killing me.

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.

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.

GSDx: Removed discards from partial colclamp support as it wasn't doing much good and definitely won't be necessary with the next stage of support. No significant functional change probably.
As before, please do a full rebuild of gsdx. I hate it as much as you but don't know how to make VS smarter about this.

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

- 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
