[cp-patches] FYI: JScrollBar fix

[Roman Kennke]

In JScrollBar we are multiplying the unit and block increment which is
wrong and leads to the JScrollBar not scrolling up at all.

2007-03-27  Roman Kennke  <[EMAIL PROTECTED]>

        * javax/swing/JScrollBar.java
        (getUnitIncrement(int)): Don't multiply direction parameter.
        (getBlockIncrement(int)): Don't multiply direction parameter.
