Complete removal of SuperVU code, it is legacy and could lead to problem for x86_64.
Let's try to reduce the code base as much as possible, will help for the port(to x64 or any others).
gsdx-ogl: always set texture parameter

* Avoid bug after a pause
* Not faster anyway
* keep old method only for gl retracer to reduce debugging noise

Remove some old&useless comment
GSdx: change post-processing directory & name.
GSdx: Some post-processing fixes & add shaders directory.
It might help if I changed this for d3d9 also :p
wx: use wx_pizza on wx2.8

The new method creates a strange gray box for some users.

Unknown status on wx3.0 (which soon will be the default)
Building, not work, bugs somewhere within wx seems? Wrong frame sent says Xorg
Correct one wxclen error due to a stray "L"...
A few more corrective, should enable to test... zzogl seems to work in 64bits... But need to test
with 4.X ogl drivers...
