let's see:
- application with freetype: 8 seconds.
- application replacing freetype with compiled-in bitmap font: < 1 second.
it seems pretty clear to me that you need to look at what you can do to
speed up freetype, and that nano-X isn't the issue here.
if you don't have a profiler, you can write rough benchmarks by
instrumenting code with whatever timers or timestamping facilities you
have available. (ticks, time-of-day, etc...)
