[cp-patches] FYI: BasicTableUI PAGE UP/DOWN implemented

[Anthony Balkissoon]

Implemented PAGE UP and PAGE DOWN (including SHIFT and CTRL modifiers)
for BasicTableUI.java.  This involved fixing a bug in JTable's
getCellRect method (it was returning the height of the entire table
instead of just the particular cell).

Also fixed a bug in JViewport scrollRectToVisible.

Patch is attached.
