I think that I figured out why things didn't look like I wanted. I am writing text on a template gif image and wasn't converting it to a RGB image. In order to get the text to show up, I was changing the image's palette to include black (rgb(0,0,0)) and then using that new palette color to write text on the image. Since the truetype fonts seem to be rendered in greyscale rather than monochrome, anything that wasn't pure black wouldn't show up on the final image.
When I work with RGB bmp files, everything looks wonderful but looks horrible when I re-encode the bmp to gif. So the moral of the story seems to be: be careful about writing truetype text in monochrome.
