[Task] rsx: Implement OpenGL MSAA

I don't know if the following is an issue related to anti-aliasing but in Resistance 3 with OpenGL renderer there are some locations with a lot of blur. It seems that a sort of auto focus is active.
For example in the forest, In the first picture everything is blur while if I move the camera down the image is adapted and becomes more crisp

That's probably just dynamic resolution scaling.

it is present also with resolution scale at 100% (720p) while there is no blur with Vulkan at any resolution scale

Ah, you see later Insomniac game's use MSAA to determine what resolution each part of the screen should be rendered at, so they can lower the resolution of some effects without lowering everything. Without it, it just lowers the whole screen's resolution making it blurrier.

Dynamic res scaling is tied to performance. In insomniac games, when you go under the target, it starts downgrading resolution of some effects similar to VRS tier 1. MSAA is used to upscale the result which is why its so blurry without MSAA. With MSAA, the image gets noticeably softer, but not as bad as without it.
This is true for all their games on that "future" engine including ratchet & clank series. Try booting something like ACiT and lock fps to something like 10, the visuals quickly start turning to soup.
