XFL svn diff

We have a project, what we are working on it more than one people.

So we use svn for version controlling.

We switched the project format from fla to xfl for see better diff viewing.

When I

 - I open the project,

 - I select something from library (do nothing else), save the project back.

 - a lot of file chang (usually vectors fillStyles)

In this case, the version controll diffs can't clearly readable because of a lot of unecessary change.
