123a192963 Use half res FBO for SSAO 
SSAO is a medium frequency effect, using half res fbo is fine and
improve performance and look by doing an additionnal bilinear filtering.
Also tune up some values.

787866909d SSAO: Do not use trilinear filtering 
Normals RTT is not mipmapped and thus bad things happened above a
certain value in the depth buffer because of trilinear filtering.

f338fbacb1 SSAO: Use a proper rand() function to generate fragment local coordinate system. 
This new level of randomness get rid of most banding effect, SSAO now looks quite good.

bd52770ceb SSAO: Avoid sampling outside of RTT_NORMAL_AND_DEPTH textures. 
It should remove artifact at the edge of the screen.

a9db4c7c3f Generate random value for SSAO sampling 
It should improve SSAO at least with grass.
However this make the algorithm even more sensitive to bad normals.
