Are there any ways to improve the font rendering in X11.app / XQuartz?

I use WingIDE for Python development and it runs under X Windows. The X11 font rendering is driving me crazy. Are there any tricks for getting better fonts in an X Server on MacOS / Lion? Sample image here . It's not so bad that I'd say it's broken, but the hinting, subpixel rendering, etc all just doesn't look nearly as nice in the X server as it does in MacOS native. I've installed XQuartz 2.7.0 binaries by hand and didn't notice any improvement in font rendering. I also tried copying Menlo.ttc into my ~/.fonts directory to have a nicer font than the X windows fonts but it's clear the X font renderer just can't match MacOS native. This 2005 OpenOffice tips article recommends replacing libfreetype but it's a pretty awkward process I haven't tried given the age of the instructions.
