/* Bert 10-Aug-2004 - MI_MAX_IMGDIMS used to be defined to be MAX_VAR_DIMS,
 * a constant defined in netcdf.h. For many years MAX_VAR_DIMS was 100,
 * but in netCDF 3.5.1 the value was changed to 512.
 * Unfortunately, the definitions of MI2_ICV_DIM_SIZE, MI2_ICV_DIM_STEP,
 * and MI2_ICV_DIM_START assume that MI_MAX_IMGDIMS is less than or
 * equal to 100.  To avoid changing the MINC API, we have to define
 * MI_MAX_IMGDIMS to 100 here.  Otherwise the miicv_inqdbl() function
 * will return bogus values for these ICV properties.
