STYLE: Replace Size var; var.Fill with auto var = Size::Filled

Using Notepad++, Replace in Files, doing:

    Find what: ^([ ]+ )(typename )?(.*Size.*[^ ])[ ]+(\w+);[\r\n]+ [ ]+\4\.Fill\(
    Replace with: $1auto $4 = $3::Filled\(
    Filters: itk*.h;itk*.hxx;itk*.cxx
    [v] Match case
    (*) Regular expression
