gsdx-ogl: correct fbmask conversion on texture shuffle
...
Fbmask is RGBA8 and must be converted to RGB5A1
=> bit 31 must be moved to bit 15

gsdx-ogl: extend cclip blending level with destination alpha blending
...
The purpose is to emulate correctly destination alpha factor
An alpha channel of 128 is 1.0 in the GS but only ~0.5 in the GPU
I think few draw call use destination alpha so impact on perf must remains small.

Actually it can partially be done with GL_ARB_shader_image_load_store

texture barrier too.

gsdx-ogl: implement a fast accurate colclip algo
...
The idea is to use a floating texture to accumulate the data and
then do a final postprocessing pass to apply the modulo
v2:
* use bounding box to
* fix vertex corruption issue
* use negative number in shader which allow to use half float (+12
fps@4x)

gsdx-ogl: optimize Cs * As + Cd and Cs * Af + Cd blending
...
Basically the code does the alpha multiplication in the shader therefore
the blend unit only does a pure addition. This way the multiplication is
accurate and accurate_blending doesn't requires a costly barrier.
This code also avoid variable duplication to make the code more separated.
Hopefully blending can be done in a separated function
It is preliminary work to support fast color clipping with HDR
v2: fix assertion compilation failure
v3: fix regression in not accurate mode
v3: Cs * As/Af is not an accumulation
Those cases don't need the Cd addition and were already optimized anyway

gsdx-ogl: try to enable sw blending for sprite rendering
...
The idea is that sprites are often use for post-processing effect (ofc except 2D games)
Most of the time post-processing supports SW blending with a small speed penality. SW
blending is more accurate so it is better to use it.

Gain: 1% at 4x on SotC (it partially compensates recent additions)
When the color is constant and equal to 128, the MODULATE mode is
equivalent to the DECAL mode. It saves 5 instructions on the FS.
