// tabpoint.h: interface for the TABPoint class.
//
/*---------------------------------------------------------------------
 *                      class TABPoint
 *
 * Feature class to handle old style MapInfo point symbols:
 *
 *     TAB_GEOM_SYMBOL_C        0x01
 *     TAB_GEOM_SYMBOL          0x02
 *
 * Feature geometry will be a UGKPoint
 *
 * The symbol number is in the range [31..67], with 31=None and corresponds
 * to one of the 35 predefined "Old MapInfo Symbols"
 *
 * NOTE: This class is also used as a base class for the other point
 * symbol types TABFontPoint and TABCustomPoint.
