Subject: Fix 1959669: "Not backward compatibility".  Update the canvas version to 0.6 and... 
X-Git-Url: https://git.pterodactylus.net/?a=commitdiff_plain;h=6876a54bece1d54df8ae3d0c9899ad8fef053ef1;p=synfig.git

Fix 1959669: "Not backward compatibility".  Update the canvas version to 0.6 and allow for a couple of missing links in older versions.  This allows, for example dooglus.rincevent.net/random/centipede-2.sifz to load again.
