           Summary: Slow down due to GetTextExtentExPointW
           Product: Wine
           Version: 0.9.16.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-gdi-(printing)
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: dsh at linux.ucla.edu


The very slow displaying of EULA mentioned in this bug report:
http://bugs.winehq.org/show_bug.cgi?id=5516
is the result of commit 73c7420c5a48d5810f30ffdca59dc36c806b4bf5, work on
GetTextExtentExPointW.  It uses an order n-squared algorithm to compute text
extent.  Displaying the EULA during installation of the Adobe product found here:
http://www.adobe.com/products/acrobatpro/tryreg.html
takes about 7-8 minutes.  Reverting the code prior to this commit causes that to
drop to a few seconds.
