New SSAA Options

[Aleron Ives]

PR 2986 changed the way Dolphin handles SSAA, and I'm curious as to how the new options compare to the old ones. Under OGL, I used to have 2/4/8x MSAA and 4x SSAA options, but now the Anti-Aliasing pulldown only has 2/4/8x MSAA, and enabling one of them causes an SSAA checkbox to illuminate. Does checking the box switch from MSAA to SSAA, meaning it's now possible to do 2/4/8x SSAA and not just 4x SSAA, or does checking the box use something like nVidia's hybrid AA method, where you get say 4x SSAA combined with 8x MSAA for 32x HSAA? The text description of the new checkbox wasn't entirely clear, so I'm a bit confused as to why you have to select an MSAA option to enable SSAA, when the two are different.
