Gregory Hainaut 92d68b70d3 gsdx-ogl: add a performance note for later
The idea will be to replace StretchRect for standard case with a framebuffer
blit. Potentially it toggles less gl state.

Worth a test on Star Ocean 3 that uses a lots this function for stencil emulation

Gregory Hainaut 419dfe0544 glsl: redo color/alpha management correction
Please test it!

GS supports 3 formats for the output:

32 bits: normal case
=> no change

24 bits: like 32 bits but without alpha channel
=> mask alpha channel (ie don't write it anymore)
=> Always uses 1.0f as blending coefficient

16 bits: RGB5A1, emulated by a 32 bits openGL texture. I think it will be more correct to use
a real 16 bits GL texture. Unfortunately it would cost several (slow) target conversions.
Anyway as a current solution
=>  apply a mask of 0xF8 on color when SW blending is used (improve Castlevania shadow)
unfortunately normal blending mode still uses the full range of colors!

This commit also corrects a couple of blending factor. 128/255 is equivalent to 1.0f in PS2, whereas GPU uses 1.0f. So the blending factor must be 255/128 instead of 2

Note: disable CRC hack and enable accurate_colclip to see Castlevania shadow ^^
(issue #380).
Note2: SW renderer is darker on Castlevania. I don't know why maybe linked to the 16 bits format poorly emulated

Gregory Hainaut 11708486d8 gsdx: allow to control the filtering of texture cache
When the RT is used as an input texture, we need to rescale it.

Previous behavior was to always uses a linear filtering (more smooth).
Unfortunately it broke some games that expected an exact value like Star Ocean 3

This commit will disable the linear filtering in normal filtering mode (filter = 0
or filter = 2)

This way, shadow of Star Ocean 3 will appear correctly in upscaling (not
100% perfect but can't do better)

Note: SO3 only requires a nearest sampling of the alpha channel but
I don't know the behavior for others games.

Gregory Hainaut b0af54d33e gsdx-ogl: better support of palette
The purpose of the code is to support alpha channel
of RT uses as an index for a palette texure.

I'm afraid that code will likely break pure palette texture. Only used
if paltex is enabled

It fixes missing shadow in Star Ocean 3 (issue #374) in Native resolution
with filter = 0  (no filtering) or = 2 (normal fitering)

Rendering explanation:
The game emulates a stencil buffer with the alpha channel

The alpha channel of the RT can contains a palette texture index (format 4HH)
The idea is to have a gradient of value in the palette (16/32/48/...).
This way you can implement a +16/-16 and even wrap the alpha value every time
you hit the pixel.

Bilinear filtering breaks the rendering because it interpolates between counts
so you doesn't have the exact count

Upscaling breaks the rendering because the RT is reused as an input texture. It means
that we need to scale it down which again create some interpolations.

Gregory Hainaut f37f3cb3cf gsdx-ogl: improve texture uploading
Initially we copy pitch by line in the PBO and tell the dma to only
use the first valid byte.

Now, we only copy useful data to the PBO. It reduce the copy and PBO memory requirement.

It seems a bit faster on native resolution

I was hoping that EGL become a standard much more faster. Currently it is an useless dep

Initially I was afraid of the size increase but it can be
higly compressed.

Sometimes image was computed inside a RT but never outputed to

Gregory Hainaut 5565544ba6 gsdx-ogl: DATE with texture barrier
Much faster for small batch that write the alpha value. Code can
be enabled with accurate_date option.

Here a summary of all DATE possibilities:
1/ no overlap of primitive
    => texture barrier (pro no setup of stencil and single draw)

2/ alpha written
    => small batch => texture barrier (primitive by primitive). Done in N-primitive draw calls.
    (based on GL_ARB_texture_barrier)

    => bigger batch => compute the first good primitive, slow but only 2 draw calls.
    (based on GL_ARB_shader_image_load_store)

    => Otherwise there is the UserHacks_AlphaStencil but it is a hack!

3/ alpha written
    => full setup of stencil ( 2 draw calls)

No barrier => draw all primitives
Barrier but without overlap => draw all primitives
Barrier with overlap => draw primitive by primitve

It will ease the implementation of accurate blending and why not date too

Atst == 2 && sprite_hack is equivalent to Atst == 1

It frees a bit in the shader selector, and reduces shader combinations.
