ramapcsx2 94cad4a61a GSdx: New hack from KrossX lets users configure their own texture coordinate offset via hacks dialog. This can be used to fine tune correction of upscale glitches versus the problems that come with it. I guess this is able to correct nearly all ghosting and bad text issues games can have! Thanks for this nice patch, KrossX :)

sudonim1@gmail.com 8a8d3c67d4 GSDX: Removed the collapsing of ge/g and le/l alpha tests in the shader code and the supporting code in the C++. This was presumably intended to reduce the number of shaders needed but a) this was never actually implemented, b) a single developer will generally not mix the functionally equivalent (with a different AREF) greater/less than with greater/less than or equal to in GS techniques, c) it really wouldn't make much of a difference to performance anyway and d) it would make an experimental change I'm working with more complicated and slower.
No change in functionality expected.

sudonim1@gmail.com 546adf52c9 GSDx: ATI strikes again. Workaround for ATI sampler bug, the same bug I found in palette sampling earlier.
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.

sudonim1@gmail.com 80ba8ff16a GSDX: Fix splinter cell double agent (and others) regression. Texture cache hits no longer depend on TEXA ever, GPU load however is increased. The last regression I think?
So, in the end I only properly understood the old code after finding all the problems with my version.  I'm not sure whether any changes I've made are improvements any more, I'll need to review it with what I've learned in mind.  This effort might've been a big waste of time.

sudonim1@gmail.com 0d9eca8668 88GSDX: Removed the "sprite hack" as it should be obsolete, fixed the vertex shader selector key function (the pixel shader was broken in the same way but with the "sprite hack" removed it doesn't matter now).

sudonim1@gmail.com 0bf64fdffd GSDX: fixed an oversight in my shader change gregory caught which removed alpha expansion for the direct sampling case, should probably fix the remaining bugs. Also set the texture sampler to point sampling when the shader will be performing its own bilinear filtering (effect on games unknown but should be an improvement).

sudonim1@gmail.com e8257df98d GSDX: made the paletted texture handling in the cache a bit more sensible to my eyes and implemented interpolation of palette entries for pixels in paletted textures when using the 8 bit textures option. Regressions in some games I think, such as Virtual On (which is very broken anyway), need to investigate what made them work (to some degree) before. Seems to change some performance characteristics favourably to my surprise, but I might just be bad at remembering framerates.

sudonim1@gmail.com 1711a26bbb GSDX: put all paletted texture samples through the same transformation from the UNORM 0-1 256 step mapping to a 0.5/256-255.5/256 mapping after seeing potential bugs with FMT_4HL and changed FMT_4HH because it seemed to be completely wrong. Nothing but 8 bit textures tested because I can't find a single game which uses 4 bit textures.

sudonim1@gmail.com 4f79c4d1cb GSDX: Fixed my inability to remember or look up (I swear that page was hiding) coordinate systems in r5279 and assumed that it was a rounding error instead. The symptom was that palette indices above around 250 were being rounded up to the next palette entry causing visible glitches (only in D3D10 for some reason). Changed the code to keep the fractional part after multiplication by 256 around 0.5 and the steps around 1.0. Should be very safe against small errors.

sudonim1@gmail.com 1df5b7ef7a GSDX: Probably fix D3D10 and maybe D3D9 (might be working anyway but I think I have it addressing texel centres now) palette lookups. I noticed that this was broken in D3D10 while fixing the Realta Nua issue in r5273.
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.

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.

sudonim1 c7aa146489 I hate D3D.
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.

sudonim1 ad21a894fc GSDx: Fixed channel masking in DX9 HW. The red and blue channels were reversed.
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.

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
