Allows picture.datatype to be used as an image.

This patch allows application to use a picture.datatype 
(subclass) object like an image using the DTM_OBTAINDRAWINFO,
DTM_DRAW and DTM_RELEASEDRAWINFO methods (and the matching
datatypes.library functions ObtainDTDrawInfoA, DrawDTObjectA,
ReleaseDTDrawInfo as documented in V45); this interface
replaces the ugly direct bitmap access.
