/*
   You can use one or more of the following defines to
   reduce the size of the compiled library.  Define the
   SKIPCANVAS macros for any canvas configurations that
   your application doesn't use.  Define the SKIPCHUNK
   macros for any chunks that your application doesn't
   process.  Define MNG_OPTIMIZE_FOOTPRINT to choose
   smaller code size over faster execution and less memory
   usage.  These macros became available in version 1.0.6.
