- FilterPostProcessor no longer use a different camera to render the fulscreen quad. This greatly simplify the multiviewport filtering handling and global uniform matrix will now be usable in fliter's shaders, because it uses the same cam as the back buffer scene.

- Changed the post.vert and post15.vert to do a very basic projection to screen, saves a 16 float uniform and replace 4 matrices multiplication with 4 MAD operations per filter.
- Used ResolutionInverse instead of Resolution in FXAA to multiply instead of dividing once per pixel
- Same in CartoonEdge
- LightScattering now uses the standard post.vert and post15.vert
- Various cleanups in SSAO
