<Swing Dev> [9] request for review: 8073001: Java's system LnF on OS X: editable JComboBoxes are being rendered incorrectly

[Andrew Brygin]

Hello,

  could you please review a fix for CR 8073001?

Bug: https://bugs.openjdk.java.net/browse/JDK-8073001
Webrev: http://cr.openjdk.java.net/~bae/8073001/9/webrev.00/

  To resolve the problem with combobox rendering, suggested fix
  adjusts text border insets in order to match dimension of the
  arrow button.

  Also, it unifies focus handling in order to get the arrow button
  updated both for cases of standard and custom editors.
  Supplied regression test verifies that the arrow button is
  updated correctly.

  Please take a look.

Thanks,
Andrew.
