[Haskell-cafe] Standalone PNG module?

I would like to load 32-bit images (RGB+alpha) for use with GLUT/OpenGL. I know GTK2HS has support for loading images, but does a standalone Haskell (wrapper) module exists for loading images? PNG or TGA would be enough for me. Yes, I could of course just use the GTK2HS OpenGL widget support, but I already have written most of my code on top of GLUT. Or I could use the SDL wrapper, but that one does not work with GHCI under Windows. Thanks, Peter
