Real fast ramped auto repeat

[GoogleCodeExporter]

I was testing the auto repeat code example and I figured out that it works 
really well when setting small values like 1 to 10. I'm trying without much 
success to make it usable when setting larger values (1 to 999). I tried to 
replace auto_repeat_first_delay and auto_repeat_repeat_delay with lower values 
but still slow for adjusting larger numbers. Any idea on how to achieve this?

Since I'm using the AVR/U8G version, I had to create my millis() function using 
timers:

ISR(TIMER3_COMPA_vect)
{
    timer3_millis++;
}

unsigned long millis()
{
    unsigned long millis_return;
    millis_return = timer3_millis;
    return millis_return;
}

I think you are getting close to the time which is required for redraw. Calling 
checkKey() more often might help, but in principle, m2tk does not handle keys 
during redraw.

void loop() {
  m2.checkKey();
  m2.checkKey();
  if ( m2.handleKey() ) {
    u8g.firstPage();  
    do {
      m2.checkKey();
      draw();
    } while( u8g.nextPage() );
  }
}
