gsdx-ogl: make VS more generic
...
Texture coordinate could be dummy/float/int integral/int normalized.
Old behavior:
* VS was in charge to select the texture coordinate
* int integral format wasn't supported
New behavior:
* Always compute all formats
* FS will be in charge to select the good format
Impact:
* VS will be slightly slower but it reduces shaders permutation from
little to 0 (won't be bad for CPU)
* FS speed isn't impacted as 2 separate code paths were already required
to support both format
* Rasterizer will be 33% slower but unlikely to be the limited factor of
the GPU
* In future we could directly use the integral format in the FS.

gsdx-ogl: accurate date regression. Bad interaction between depth & DATE
...
In the DATE42 algo, first pass must find the primitive that write the
bad alpha value. If depth test is fail, alpha value won't be written therefore
you mustn't keep the primitive id.
In theory to ensure 100% correctness, depth would need to be fully executed
(currently depth write is disabled). However it requires to copy the depth buffer.
It is likely bad for the perf.
