[visionegg] Re: still no Leopards?

Hi Alex,

I haven't upgraded my Mac to 10.5 yet, and I don't feel any burning
desire to upgrade at the moment, either. My biggest worry is that a lot
of stuff in the lower layers will be broken (namely pygame/SDL),
although I haven't personally looked into it.

My present VE effort will go towards pushing out a release based
more-or-less on the subversion repository, which should has working
numpy support. And then after that I'd like to experiment with a
pyglet-based version so that we can drop the dependencies on pygame and
perhaps pyopengl. The primary sticking point so far is that pyglet does
not have a set_gamma_ramp() functionality. Martin Spacek has put some
efforts into getting the set_gamma_ramp() functionality into pyglet, but
the lead developer there doesn't seem to think that set_gamma_ramp() is
suitable for inclusion in pyglet so we may have determine how best to
deal with the situation. Although, if we decide pyglet is the way to go,
I'm sure we can figure something out. If all else fails, we can maintain
our own copy of pyglet with the set gamma function added. Anyhow, this
is a long way of getting to the point that I think pyglet will work on
10.5 pretty immediately, so doing this effort could get us there
regardless of any SDL issues.
