/* The below math formula causes the following to happen on the slider control:
* From 0 to 1 megabit/sec (1000000 bits/sec), the scale is linear.
* From 1 megabit/sec to 1 gigabit/sec, the scale is logarithmic.
* The formula first converts the above numbers from bits/sec to octets/sec.
* Then it takes the Log base 10 of that octets/sec number.
* Finally, it aligns the start of the log scale with the linear scale, by subtracting Log base 10 of 1 megabit/sec (125,000 octets/sec), minus 1.
