I managed to create Jam files for the hqx library files and get them
running, next task will be to try and integrate it with my program to do
BeOS icon scaling, hopefully the results will look dramatically better, I
have tested only on regular bmp's I downloaded off the Internet, now I need
to test with BeOS icons.
