    Martin and I had a discussion on IRC last night (after this email was sent) and we finally reached a consensus on the correct behavior. Marc (uwog) and Tomas also seem to agree with this, so let's go and actually implement it:

    "If a run is not transparent, draw the color/image into the background rectangle. If a run is transparent, it should ask its parent container to draw into the given background rectangle, until the parent isn't transparent or the parent == the document."

    For the case of background images, I suggest we investigate Tomas' suggestion, which is basically what Martin and I had discussed the previous evening. It would follow the same semantics as the above, but hopefully would optimize so as to blit only the required RGBA bits onto the screen.
