I profiled navit on my desktop using valgrind and a major part of the 
time required for rendering the map is spent on rendering the fonts for 
the street names, etc to bitmaps. The font part of my patch makes navit 
use the freetype cache subsystem. However, it does not yet work as 
intended. It still seems to render the font outline too often. It is, 
however a step in the right direction. I have posted on the freetype 
mailing list how to configure the cache to reduce the number of outline 
rendering runs, but have not yet received an answer.
