fixed point math sharpening filter
Does anyone have a nice fixed point math 1 channel sharpening filter?
Should be done in C using fixed point math.

possible declaration:

    void sharpen( uint8_t *src, uint8_t *dest, int srcdst pitch, int height );

Best algorithm realization gets 300 rep bounty :)
