Hi, @czarnyafgan !

Yep, I haven't forgot about antialiasing just thinking about in engine api for that in background :)
So, question to developers around here: how in engine api should look a like?

Current in engine api look like this:

// allocate frame buffer with 4 color attachments + zbuffer
fboGBuf     = device.frameBuffer(lightingBuf,gbufDiffuse,gbufNormal,gbufDepth,zbuffer);

// render-pass (need a better name for it), - controls Load/Store operations
gbufPass  = device.pass(FboMode(FboMode::PreserveOut,Color(0.0)),
                        FboMode(FboMode::PreserveOut),
                        FboMode(FboMode::PreserveOut),
                        FboMode(FboMode::PreserveOut,Color(1.0)),
                        FboMode(FboMode::PreserveOut,1.f));

Need an api to express:

1. Lazy allocated attachment, for MSAA texture
2. Resolve api (I think store op FboMode::Resolve should be fine)
3. While on that would be nice to cover shading-rate-attachments and pixel-density-map
