BScrollBar arrows dont respect range (when min = 0)

Description

BScrollBar in MouseDown() assigns a temporary float scrollValue = 0.0, and then determines a hitcheck on the arrows. It decrements scrollValue for left arrow case ARROW1:

scrollValue = -buttonStepSize; break;

And then later on checks if (scrollValue != 0.0) in order to process the action.

This forces developers to keep a valid range from 1 - max, instead of from 0. The default for scrollValue should not be zero since it prevents min range from being zero, even though allowed the the BeBook API.
