        Description

        The up & down buttons in the JScrollBar don't animate properly. Here is what should happen (assuming the bar is not focused):

          * If the mouse is not on the scrollbar, then the thumb should be gray, and there should be no borders around the up/down buttons
          * If the mouse moves over the thumb, the thumb should animate toward light-blue and the border/background of the up/down buttons should animate from translucent to opaque
          * If the mouse moves back out (after hovering over the thumb), the JScrollBar should animate back to the original state (no background/border for up/down buttons, gray thumb)
          * If the mouse moves over the track, then the background/border of the up/down buttons should fade in. If the mouse then leaves, they fade back out. The thumb doesn't change color
          * If the mouse moves over the up/down button, then the background/border of the button should fade to opaque, and should animate toward a light-blue color. Reverses when the mouse moves off the button

        What currently happens:
          * Nothing happens when the mouse hovers over the track
          * When hovering over the thumb, it appears that the background/border of the up/down buttons immediately pops into being opaque, instead of animating
          * When leaving the thumb, the background/border of the up/down buttons immediately goes to translucent, instead of fading out. It should fade at the same rate as the color drains from the thumb
          * When hovering over the up/down button and leaving it, the color fade and the opacity fade should happen at the same rate. They don't. The Color takes longer to fade (apparently correctly), while the opacity diminishes apparently immediately. Also note that the other button (ie: if on the up arrow, the down arrow button) should fade at the same rate. It doesn't currently.
