Scrolling: JViewport, JScrollPane, and Related Classes

Other Swing Changes

New JViewport scrollMode Property

Interactive scrolling speed has proven to be perhaps the most important factor in users perception of overall swing performance. 1.3 adds a new optimization, called "BLIT_SCROLL_MODE" (now the default) that copies unobscured areas of the components heavy weight ancestor to effect a scroll. Previously we had offered a related optimzation that managed a per viewport backing store image. Although still supported, the backingStoreEnabled property has been deprecated.
