Subversion provides its own client library for accessing the virtual file
system. You won't have to work with the DB directly. It also provides an
abstracted recover facility in one of its utilities (in case of stale locks).

I said hybrid delta algorithm for binary diffs. I didn't say
straightforward A - B diffing.

Even if your images are black and white, they are most likely stored in a
compressed format (if a Subversion based GIMP file format was ever
invented), and if such compressed files are revisioned, no
generic algorithm is going to give you a good difference.

The whole Subversion thing was a far fetched *idea*. An alternative,
which is most definitely going to be blown off as there are more
reasonable ways of implementing the GIMP file format which are not far
