Gregory Hainaut b17803bb34 gsdx-ogl: wipeout of GL_ARB_bindless_texture
Code is completely broken. It doesn't help to improve speed.

Remove 200 lines ;)

Gregory Hainaut b4c04ed00a gsdx-ogl: wipeout subroutine code
Code was completey bitrotten
Code was a partial test (and yet 500 lines already)
Shader is more and more complex and multithreading support greatly
reduce the cost of shader switch

Gregory Hainaut e245b27c97 gsdx-ogl-debug: allow to dump various ps shader
Nvidia allows to get the ASM of the shader of the compiled shader. It is useful
to check the performance.

It also allow me to compile most of shader code path for QA

Dump is enabled in linux replayer + debug_glsl_shader = 2

Gregory Hainaut a1bfb237e6 Partially Revert "gsdx-ogl: drop support of GL_ARB_clear_texture extension"
This reverts commit 03e72781aa.

Let's add back the clean texture pointer

Gregory Hainaut cc4713d379 gsdx-debug: extend ogl debug capabilities
Group opengl calls into a nice name.

Apitrace shows them in a tree format that support folding. Previously it
was a long flat list (10K-40K of lines by frame)

I align the call number with the internal s_n variable. This way it is
easy to map GSdx dump output with the GL debugger :)

Gregory Hainaut 03e72781aa gsdx-ogl: drop support of GL_ARB_clear_texture extension

We use it to clear the RT but we generally use it right away so
we don't avoid the FB attachment.

Ifdef all gl code not supported on gles3 (note some will be reenabled for gles3.1)

Note: it probably doesn't run anymore. My Nvidia driver doesn't support
yet egl/gles so I can't test it. Feel free to contribute.

gregory.hainaut 84895eadd9 gsdx ogl: correct most of Z-depth issue
Best setting if you driver support GL_NV_depth_buffer_float => GL_NV_Depth = 1 & logz = 0
Otherwise => GL_NV_Depth = 0 & logz = 1

Explanation of the bug:
Dx z position ranges from 0.0f to 1.0f (FS ranges 0.0f to 1.0f)
GL z Position ranges from -1.0f to 1.0f (FS ranges 0.0f to 1.0f)

Why it sucks:
GS small depth value will be "mapped" to -1.0f. In others all small values will be 1.0f! Terrible lost
of accuraccy.

The GL_NV_depth_buffer_float extension allow to set the near plane as -1.0f.
So
"GL z Position ranges from -1.0f to 1.0f (FS ranges 0.0f to 1.0f)"
will become
"GL z Position ranges from -1.0f to 1.0f (FS ranges -1.0f to 1.0f)"
and therefore
"z posision [0.0f;1.0f] will map to FS [0.0f;1.0f]" as DX

Yes we just get back all precision lost previously :)
However you need hardware (intel?) and driver support (free driver?/gles?) :(

gregory.hainaut e01c6cd9ce gsdx ogl: the proof of concept commit
* GL_ARB_shader_subroutine for perf
fix for nvidia => add missing shader declaration. Nvidia got +4fps on colin3 :) 

For the moment only 2 PS parameters are supported. Code need to be extended to support others games that often
switch shader program (like xenosaga).
require GL4 class hardware and the option override_GL_ARB_shader_subroutine = 1
Note: strangely on AMD linux it is slower!

* GL_ARB_shader_image_load_store for accuraccy (Date)
Use a signed integer texture and reenable color buffer writing

Current status: Amagami_transparency.gs & P3_battle_shadows.gs are now working on Nvidia with a small perf impact.
Current implementation detail:
1/ setup the standard stencil as before
2/ on remaining pixel, draw once to compute first primitive that will write a fail alpha value.
3/ final draw based on primitive id of step 2

Note: I think we would get a bad behavior if depth test&mask are enabled on step 2/3
Note2: on my limited testcase the perf impact was on CPU. It would be possible to merge step1&2 to nullifying it (could 
even be faster actually), however it would require more GPU power.

Again require GL4 class hardware. And the option UserHacks_DateGL4 = 1

gregory.hainaut 07605941ef gsdx ogl:
* some preliminary work to test/benchmark bindless texture in the future (glsl was not yet updated)
Bindless texture allow to get a GPU texture pointer and then set it directly
to the shader as a basic uniform.
=> no more texture unit selection/validation
=> no more texture validation neither texture hash lookup

3rdparty: update gl header to the latest gl4.4

gregory.hainaut 0f603a98d5 gsdx ogl: Test the ARB_shader_subroutine GL4.0 extension
The idea was to replace shader program swith by pointer function calls inside
shaders.  At least parameters that are often changed between draw call. So far
I only ported atst and colclip. Unfortunately code is "slower" (on GSdx standalone).
For the moment keep the code but disabled.

If I understand well the validation of program is done in the "driver thread"
but the additional call are done in the overloaded MTGS thread. Apitrace
profiling shows faster GPU draw calls. Another possibility is that the driver still
need to validate the draw call because of others state change.

Here some stats on colin3 (90 frames):
without subroutine: UseProgram 125246
with subroutine: UseProgram 2906, subroutine 125945 => 3605 extra calls overhead (not
all parameters are ported to subroutine)

* move most of gl states into a separate namespace. Extend it to depth/stencil/blend micro state

* Only setup blend state of first drawbuffer
* Don't request anymore a debug context on dev/release build

gregory.hainaut 34045eb8f7 gsdx ogl: AMD users upgrade to 13.8 now ;)

=> a bit faster and probably got some margins for the future

* preliminary work for GL4.4 extensions (ARB_clear_texture & ARB_multi_bind). Disabled until I got a 4.4 driver
Note: I plan also to use ARB_buffer_storage
* compute texture gl option in the constructor (avoid a couple of swith case)
* redo texture unit management. Unit 0-2 for shaders, Unit 3 for texture operations. MultiBind will allow to bind 
shader input without disturbing texture binding points.
