<Swing Dev> [9] Review request for 8171808: Performance problems in dialogs with large tables when JAB activated

[Mikhail Cherkasov]

Hi all,

Could you please review the fix:
http://cr.openjdk.java.net/~mcherkas/8171808/9/webrev.01/
for the following issue:
https://bugs.openjdk.java.net/browse/JDK-8171808

When JAWS asks java how many visible elements in the frame are,
  java goes through the whole tree of component and asks each whether it 
visible or not.
During this java creates accessContext for each element, so this 
requires to get data from model.
So if user uses lazy loading or model is large, this counting makes app 
to freeze.

I reduced the number of components that should be checked for visibility,
if we get to a row that is invisible, there's no sense to check next 
rows, the same for columns.

Thanks,
Mikhail.
