Default value for "ScrollStep" in ScrollAreaGadget()?

[Lebostein]

I would like to use the #PB_ScrollArea_BorderLess flag. But I can't do that without having to specify the “ScrollStep” parameter. Unfortunately, there is no default value in the documentation that I can use without changing the previous behavior.

Edit: The default value for "flags" is also missing in the documentation.

I think default value is 10, but you can read the value before to be sure.
