Read data from a DXF file into a DXF VIEW entity.
The last line read from file contained the string "VIEW".
Now follows some data for the VIEW, to be terminated with a " 0" string announcing the following table record, or the end of the TABLE section marker ENDTAB.
While parsing the DXF file store data in view.
