From: Andreas Baierl <ich...@imkreisrum.de>
There is some bogus code, which calculates the variable bright four times.
This typo is corrected and also the calculation is adapted to deliver the
right range for bright, contrast, saturation and hue from 0-63.
Before, when the maximum value (100) was given to the function,
calculation returned 64, which is wrong due to the possible range 0-63.
