[SDL] SDL 1.3 roadmap...

It was needed for DirectX 5, which is dropped in SDL 1.3.

Yes, where possible.

Possibly, there are a lot of situations where vbl syncing isn't possible,
so if it's added it'll be after the core features are done.

Yes, of course.

It does right now.  Direct3D and OpenGL are actually used to implement the
SDL 1.3 2D interface.

Test case?

I'd actually like to add an option to do aspect-constrained stretching,
and of course fix the issues in general.  The move to largely using OpenGL
where possible to implement 2D video makes it a lot simpler to make sure
everything works consistently on the various platforms (sorta!)

Thanks!
