        [WINCE] Add additonal methods to BitmapInfo.
        https://bugs.webkit.org/show_bug.cgi?id=42071

        Added a parameter to create 16bit BitmapInfo and
        some additional accessors for the WinCE port.

        Set bmiHeader.biSize only at constructor.

        * platform/win/BitmapInfo.cpp: Added property svn:eol-style.
