[Insight-users] change origin and spacing tags for Dicom output

[Karthik Krishnan]

Some time in future it is planned to support writing of DICOM files in a 
consisitent manner from ITK, so you could just instantiate a writer like 
you do for all other file types and it would write a series of dcm files 
for you.

See http://www.itk.org/Wiki/Proposals:Writing_DICOM_from_non-DICOM

The idea is to have ImageSeriesWriter populate an array of 
MetaDataDictionaries, with each element of the array (a 
MetaDataDictionary) containing origin info for an image and that 
GDCMImageIO would use this to write out the origin in the image being 
written.
