  What is the correct behaviour?

  For example, let's suppose that we are calculating a pixel which is
located at the crossing of the edges of two objects.
  One object is red (<1,0,0>) and takes 50% of the pixel area. The other
object is green (<0,1,0>) and takes 25% of the pixel area. The last 25%
of the pixel is background.
  What should be the RGBA values for that pixel?
