This fixes http://code.google.com/p/chromium/issues/detail?id=2803, which was an issue with windowless flash videos not playing if there were more than 15 instances of flash on the page. The bug occurs because we pass in the HDC of the parent window in the update geometry sequence. The webkit plugin implementation does not do this and only passes the hdc in Paint.
This fixes http://code.google.com/p/chromium/issues/detail?id=2803, which
was an issue with windowless flash videos not playing if there were more
than 15 instances of flash on the page. The bug occurs because we pass
in the HDC of the parent window in the update geometry sequence. The webkit
plugin implementation does not do this and only passes the hdc in Paint.

The fix is to mimic this behavior.
