* The following structure is the ClanLib file reader driver for MikMod.
* In fact MikMod core functions expect an MREADER struct, so the first
* field of MCLANLIBREADER (core) is an MREADER, and this way the MikMod
* code can access correctly all the fields of the MREADER core struct,
* while we provide an additionnal pointer (input) to handle the file,
* which is a CL_InputSource in ClanLib's case.
* This method might look like an ugly hack but MikMod does this internally,
* with an MFILEREADER struct casted an into a plain MREADER.
