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.
