From c2d8810625892a8bedcaa192df9b4165e46609ee Mon Sep 17 00:00:00 2001

Subject: Move Inkscape::IO::fixupHrefs to Inkscape::XML::rebase_hrefs in new
 file xml/rebase-hrefs.*.  Give it the old and new base directory, so that it
 can change hrefs without relying on sodipodi:absref. Also create a new
 function sp_repr_save_rebased_file that changes all xlink:href attributes as
 it writes them, so that we don't need to modify the owning document. 
 (Especially useful for "Save a copy" or exporting.) extension/system.cpp:
 (Inkscape::Extension::save): Don't call sp_document_set_uri even temporarily
 other than at the same time as calling rebase_hrefs.  (Otherwise, existing
 relative hrefs will point nowhere.) When exporting plain SVG, change the
 relative hrefs according to the destination filename.
