Depending on the hardware/driver we have to work with a huge variety of 
levels, for example with the default driver my laptop has from 1-7 while with 
the "raw" driver it has from 1-2500.

Image we increase 10 on every step, it will take a a while to go from 1 to 
2500 and it won't work with the 1-7 case.

So we do some math to make sure that we offer a consistent behavior across all 
hardware:

Accepting a patch that makes it possible to modify this can be considered, 
specially taking into account that special hardware might need this.
