Function pointer was mangled to avoid any collision. Nowadays all symbols
are hidden so no risk of collision.
Syntax is nicer beside it would allow to put back GLES3.2. I think it
supports most of the used extension.
glActiveTexture & glBlendColor are provided without symbol query.

easy to map GSdx dump output with the GL debugger :)

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?) :(
