+Description: gdcmDicomDir and SQItem creation
+Date: 2004 Nov 16
+Attributed:
+Details: DicomDir creates some SQItem (by new). Then, it creates
+ the corresponding DicomDirPatient, etc. using the content of the SQItem
+ (the content is composed with some DocEntry's that can't be destroyed).
+ So, if the SQItem is deleted, then it's content is deleted to. But the
+ DicomDirPatient, etc. use the content of the SQItem. Then, the SQItem can't
+ be deleted, and when have memory leaks

+Description: [BUG] Better handling of unfound Dicom dictionary.
+ When gdcm doesn't find the Dicom dictionary (because it's
+ path to the directory of dictionary is uncorrect, either
+ because the install relative layout was broken after file moves
+ or because the environnement variable GDCM_DICT_PATH is
+ unpropely set), gdcm will:
+ 1/ print a warning
+ 2/ throw an exception (that is internaly UNcatched by gdcm)
+ that in most cases provoques the caller application to
+ exit uncleanly (uncatched excpetions in fine call abort() ).
+ Additionaly on Win32 the warning print isn't displayed because
+ exiting occurs prior to cerr or cout is flushed properly.
+Date: 2004 Oct 15
+Attributed:
+Details: fixes (from dirty to clean)
+ 1/ force Win32 to flush it's buffer so at least the user gets some
+ reason why it's application exited (when called in command
+ environement). Note: it looks like the "cerr << flush" fails. Sigh.
+ 2/ within gdcm catch the exception, display a decent warning, and
+ return to caller.
+ 3/ see the comment below on how to enhance the API and fix things
+ really cleanly.
+Comments: ENH proposal:
+ The caller migth not be aware of the path to the dictionaries
+ on invocation of gdcm (think this path is set by the Interface
+ because the caller wants to skip the default gdcm dictionary in order
+ to provide his own ones e.g. another language based one).
+ Hence, gdcm should postpone the parsing of the default dictionary
+ instead of doing it on library entry.
+ This would enable two things:
+ - It would give a chance to the caller to set the path to
+ the dictionaries he whishes to use, through a call to
+ newly created DictSet::SetDictionaryPath( string ).
+ - It would avoid the burden of using the GDCM_DICT_PATH
+ environnement variable and enable GDCM CONTROL FROM WITHIN
+ THE API. Optionaly, if the caller didn't use the API to
+ provide his prefered path, gdcm could still default to
+ GDCM_DICT_PATH...

+Description: vtk/vtkGdcmReader doesn't positionate the normal to the image
+Date: 2004 Oct 1
+Attributed:
+Details: vtkGdcmReader::CheckFileCoherence() sets the DataOrigin[i]
+ but doesn't set the plane (image seen in 3D) normal (is it
+ possible any how). This plane normal could be extracted from
+ the "orientation" info of the gdcmHeader ( refer to
+ grep "Orientation" Dicts/dicomV3.dic).
+ Problem exhibiting this defect: cine loop on a stack of images
+ whose Origin is correct, but whose normal is not set will
+ plainly suck !
