You can set the background color of a TextRoi using the
setBackgroundColor() method, which was added in the 1.43h daily build.
I updated the JavaScript text overlay example at
http://rsb.info.nih.gov/ij/macros/js/TextOverlay.jsto use the method.

Here are some example plugins that use display lists to draw
non-destructive graphic overlays:

I think what you are looking for is the ImageCanvas.setDisplayList()
method. I updated the ImageJ API documentation at
http://rsb.info.nih.gov/ij/developer/api/to v1.43h.
