SYNOPSIS

	handle = ObtainDTDrawInfoA (o, attrs);

APTR ObtainDTDrawInfoA (Object *, struct TagItem *);
handle = ObtainDTDrawInfo (o, tag1, ...);
APTR ObtainDTDrawInfo (Object *, Tag, ...);

FUNCTION

	This function is used to prepare a DataTypes object for
drawing into a RastPort.
This function will send the DTM_OBTAINDRAWINFO method
to the object using the opSet message structure.

INPUTS

attrs - Additional attributes.

RESULT

	Returns a opaque handle that must be passed to ReleaseDTDrawInfo()
when the application is done drawing the object.

add the object in question to a window or requester and use
ObtainDTDrawInfo() on it.
