David, I'm pretty sure I got TIFF files to display with transparency a while back. The files were RGBA, ie included an alpha channel and I had masked out a background. Can you pre-process your images and add an alpha channel with 0 where you want transparency? You should be able to find or make a test image pretty fast to see if it works.
