* 100% Match of MxDSFile * ...almost, MxDSFile::Open is still not quite matching but all of the other methods are 100% matching. * Turns out that most of the virtual methods and some of the members are actually on the MxDSSource base class, which I've pulled out as part of this. * In order to implement the methods I added the MXIOINFO class, which seems to be a thin wrapper around the MMIOINFO windows structure. We can tell this because MMIOINFO::~MMIOINFO was included in the DLL exports, and calls down to a function which deconstructs something looking exactly like MMIOINFO. * Add mxdssource.cpp * mattkc feedback * some accuracy improvements * Use FOURCC macro * Tirival solve in mxioinfo.cpp * Update mxdsfile.cpp 0xFFFFFFFF -> -1 --------- Co-authored-by: Christian Semmler <mail@csemmler.com>
