--- Comment #4 from Stefan Berndt <stefan.berndt at imoriath.com> ---
Just for fun and for learning i have tried to get more speed with pure
assembler code. After all i was impressed how good the GCC already does the
job. The only way to get it faster than GCC was to hardcode every pixel of the
character set. Its made for 16 BpP only and reached 1 milion lines at 251
Secends. A very poor result for this crazy huge pice of code. Only for your
entertainment i will show you the resultig file.
