I want to be able to change what the steps are based from.

Example:

Step: 5
Min: 13
Max: 29
Value: 16

With these configs, the possible values of the slider are:

13, 18, 23, 28, 29 (with an initial value of 16 that cannot be selected after you slided to something else)

But it would be nice to be able to set 0 (or anything else) as the starting point for steps, which would gives:

13, 15, 20, 25, 29
