    Switching to 64-bit checksum: substituted sal_uLong with BitmapChecksum
    
    A typedef sal_uLong      BitmapChecksum;
    has been added to include/vcl/checksum.hxx
    
    Wherever needed sal_uLong and sal_Int32 has been substituted with
    BitmapChecksum.
    
    A BITMAP_CHECKSUM_BITS constant equal to the amount of bits used by the
    BitmapChecksum type has been defined and used in
    `GraphicID::GetIDString` (vstools/source/graphic/grfcache.cxx).

commit ebb0dc14547e698d7b53005178063da72d48f075
Author: Marco Cecchetti <marco.cecchetti at collabora.com>
Date:   Wed Aug 26 13:50:57 2015 +0200

    Added support for computing 64-bit checksum of bitmap in OpenGL
    
    Added a C++ and a GLSL implementation of a 64-bit CRC algorithm.
    
    Changed hardcoded checksum value in ooxmlimport unit test (testN777345).
