    - src/gdcmDocument.[cxx|h] Parse7Fe0 renamed to ComputeRLEInfo.
      This is because Parse7Fe0 used to parse the pixels to compute the
      length. This task was passed over to FindDocEntryLengthOB() a long
      time ago, EXCEPT I had forgotten the OW case...
      Hence Parse7Fe0 was no longer necessary. When renaming to ComputeRLEInfo
      we just recylce the code for parsing RLE fragments and computing
      offsets.
