It is maybe a little bit late to answer this mail, but at the end of february my library (http://hackage.haskell.org/package/SVGFonts) was in not such a good state to advertise it. But now it has reached version 1.0 and a lot of errors have been corrected! It has most of the capabilities of freetype2, ftgl and pango in only 44KB of code. This is about 100 times smaller than freetype2. It also has a very easy and powerful interface without forcing you into using the IO monad. It is a native Haskell library without the need to install any C-library, so it should work on every operating system. Very interesting! =)

It is also quite fast. The example that comes with the library generates 62 character textures in about a second. So, is 62 chars/s fast? And where is most of the time spent?

Cheers,

It is probably not fast. A graphics card can raster high resoultions 100 times a second. But font libraries can't use this rasterization mechanism (I guess) because of autohinting (making fonts look good on low resoultions). For me it is fast enough. The last time I profiled the xml parsing was the biggest problem. But I haven't profiled for quite a while because of Ticket #282 of cabal. I don't want to manually compile every library with profiling.
