I know these things because I've written subroutines that do it. To draw a smooth circle, my routine copies a square of the background into memory, blowing it up four times, over which a jagged circle four times final size is drawn. Then I have it do weighted supersampling in bringing it down to final size. The result is antialiasing of good quality with accurate color blending. If speed is not an issue, it could be even smoother by drawing larger than 4x before reducing. When doing it manually, I use the same principles with available free software. And I try to limit the blurring to the edges of the object being pasted into the scene.
