I just want to point out that while that switch is "Continuously Rasterize" for vector layers, it is "Collapse Transformations" for comp layers.
While the on-screen effect can sometimes be the same (keeping layers sharp), the function itself is very different. Collapse Transformations tells Ae NOT to rasterize the comp layer and then apply masks, effects, transforms, and layer styles to the one composite layer. Instead, it tells Ae to transform and composite each layer within the comp individually into the main containing comp, effectively pulling them into the containing comp.
