Gregory Hainaut 7d3c850813 gsdx ogl: improve ST/Q precision 
When a float overflow is detected, geometry shader is disabled. And ST/Q is done on the CPU

It will help
Issue 551
Issue 1684

Gregory Hainaut 611239db5c gsdx: handle float overflow on Q in vertex trace 
Replace the fast reciprocal with a slower division when we detect a too big Q value.

Improve #551, #1684

Gregory Hainaut b54a824abd gsdx: split texture filtering option 
Bilinear applies to all renderer
* Common code done in GSVertexTrace
* Extend it with forced but sprite (trade-off between linear/upscale glitches)
* Linux GUI option was moved at the top with the renderer selection

Trilinear is moved to OGL hack

close #1837

Thanks to Flatout for the review and feedback.
It will take care to update the Window GUI :)

Gregory Hainaut 211c7745de gsdx: don't try to correct depth in primitive trace 
Avoid to go above the maximum size allowed by the format

Gregory Hainaut 49d5c4260f gsdx state: post fix depth tracing 
The main FindMinMax methods is perf critical so instead I created a separate function
to ensure the constness of the depth

Fix letter regression on Xenosaga3

Gregory Hainaut 4612b79575 gsdx: add a warning on vertex trace 
Due to a division by 2, depth lsb bit is always 0

I'm not sure it is critical but let's keep a note for the future

Jonathan Li e5ea4cc5d4 gsdx: Defer vector initialisation to GS/GPUinit 
It can cause PCSX2 to crash if the instructions aren't supported.

Gregory Hainaut 5fb8c7e65c gsdx: initialize members in constructor of objects 
A couple of useless members were removed too.

Also fix wnd initialization

Coverity:
CID 146955 (#1 of 1): Uninitialized pointer read (UNINIT)
18. uninit_use: Using uninitialized value wnd[i].

gabest11 5d9a5b6ee6 GSdx: there was a float-int conversion overflow in vertex trace, texture coord min/max could have been detected wrong, silent hill origins should look better now.

gabest11 1d759c852d GSdx: When mipmapping is on, LOD is calculated per pixel, it isn't used for anything, but it's there. I cannot really measure any significant slowdown, but rest of the fun is yet to come.

sudonim1 8c0fc49f61 GSdx: Removed DX10 support in favour of DX11. I am told that this shouldn't affect anyone and it reduces code duplication. (DX11 was already missing some changes in DX10, I have ported them.) 
GSdx: Removed OpenGL "support".  Nobody showed any interest in getting this working.
GSdx: Removed PS1 GPU support.  pcsx2 does not use this and it is unmaintained, likely broken, and frequently confuses intellisense.
GSDumpGUI: Use the correct export for the library name, was using the PS1 version.

If any of the above code is needed in the future, we have this wonderful technology called version control.

gabest11 83b15dbac0 GSdx: 
- 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

gabest11 b284fae2d5 GSdx: moved around some code and optimized texture caching a bit, there may be a slight speed-up in hw mode for those games that use many textures.
