I think I'm barking up the wrong tree. I found, in a previous statalist discussion, "At the moment Stata does not allow a level of transparency in the graphics engine." It seems that transparency support would be necessary for overlaying a graph on top of an image. Indeed, when I try exporting .pngs with regions having "zero" fill, the resulting file is still opaque.
