/**  convertMap.h
Functions for converting  from one Map form to another 
and extracting smaller maps. There are four polymorphic
functions.   The general format is

convertMap(MapType * source,MapType * target, Point ul, Point lr)

MapTypes can be - BitMap, RLEMap, or VRLEMap
source - the map to be converted from
target - The map to be converted to.  Memory will be allocated
         for target's contents. 
ul and lr mark a range to copy.   If either are the global var NOPNT,
the entire map will  be copied.

Functions return a MapStatus which will be VALID or OTHERERROR
if there was an error in the conversion.  An error might be due
to a user specifying an out of range ul and lr.
