[9] Review request for 8036110 In TextField can only select text visible or to the left of the cursor

[Alexander Scherbatiy]

Hello,
Could you review the fix:
  bug: https://bugs.openjdk.java.net/browse/JDK-8036110
  webrev: http://cr.openjdk.java.net/~alexsch/8036110/webrev.00

  This is a regression from the fix 7092551 where the EDIT control has 
been changed to the RICHEDIT.
  GetScrollInfo(hWnd, SB_HORZ, &scrollinfo) returns zero values for the 
RICHEDIT if WS_HSCROLL style is not set.

  The fix enables the horizontal scrollbar before the GetScrollInfo 
call and disbles it after the call.

Thanks,
Alexandr.
